Pantone’s Palette Generator enhances creative exploration with agentic AI on Azure
Color can be powerful. When creative professionals shape the mood and direction of their work, color plays a vital role because it provides context and cues for the end product or creation. For more than 60 years, creatives from all areas of design—including fashion, product, and digital—have turned to Pantone color guides to translate inspiration into precise, reproducible color choices. These guides offer a shared language for colors, as well as inspiration and communication across industries. Once rooted in physical tools, Pantone has evolved to meet the needs of modern creators through its trend forecasting, consulting services, and digital platform. Today, Pantone Connect and its multi-agent solution called the Pantone Palette Generator seamlessly bring color inspiration and accuracy into everyday design workflows (as well as the New York City mayoral race). Simply by typing in a prompt, designers can generate palettes in seconds. Available in Pantone Connect, the tool uses Azure services like Microsoft Foundry, Azure AI Search, and Azure Cosmos DB to serve up the company’s vast collection of trend and color research from the color experts at the Pantone Color Institute. reached in seconds instead of days. Now, with Microsoft Foundry, creatives can use agents to get instant color palettes and suggestions based on human insights and trend direction.” Turning Pantone’s color legacy into an AI offering The Palette Generator accelerates the process of researching colors and helps designers find inspiration or validate some of their ideas through trend-backed research. “Pantone wants to be where our customers are,” says Rohani Jotshi, Director of Software Engineering and Data at Pantone. “As workflows become increasingly digital, we wanted to give our customers a way to find inspiration while keeping the same level of accuracy and trust they expect from Pantone.” The Palette Generator taps into thousands of articles from Pantone’s Color Insider library, as well as trend guides and physical color books in a way that preserves the company’s color standards science while streamlining the creative process. Built entirely on Microsoft Foundry, the solution uses Azure AI Search for agentic retrieval-augmented generation (RAG) and Azure OpenAI in Foundry Models to reason over the data. It quickly serves up palette options in response to questions like “Show me soft pastels for an eco-friendly line of baby clothes” or “I want to see vibrant metallics for next spring.” Over the course of two months, the Pantone team built the initial proof of concept for the Palette Generator, using GitHub Copilot to streamline the process and save over 200 hours of work across multiple sprints. This allowed Pantone’s engineers to focus on improving prompt engineering, adding new agent capabilities, and refining orchestration logic rather than writing repetitive code. Building a multi-agent architecture that accelerates creativity The Pantone team worked with Microsoft to develop the multi-agent architecture, which is made up of three connected agents. Using Microsoft Agent Framework—an open source development kit for building AI orchestration systems—it was a straightforward process to bring the agents together into one workflow. “The Microsoft team recommended Microsoft Agent Framework and when we tried it, we saw how it was extremely fast and easy to create architectural patterns,” says Kristijan Risteski, Solutions Architect at Pantone. “With Microsoft Agent Framework, we can spin up a model in five lines of code to connect our agents.” When a user types in a question, they interact with an orchestrator agent that routes prompts and coordinates the more specialized agents. Behind the scenes an additional agent retrieves contextually relevant insights from Pantone’s proprietary Color Insider dataset. Using Azure AI Search with vectorized data indexing, this agent interprets the semantics of a user’s query rather than relying solely on keywords. A third agent then applies rules from color science to assemble a balanced palette. This agent ensures the output is a color combination that meets harmony, contrast, and accessibility standards. The result is a set of Pantone-curated colors that match the emotional and aesthetic tone of the request. “All of this happens in seconds,” says Risteski. To manage conversation flow and achieve long-term data persistence, Pantone uses Azure Cosmos DB, which stores user sessions, prompts, and results. The database not only enables designers to revisit past palette explorations but also provides Pantone with valuable usage intelligence to refine the system over time. “We use Azure Cosmos DB to track inputs and outputs,” says Risteski. “That data helps us fine-tune prompts, measure engagement, and plan how we’ll train future models.” Improving accuracy and performance with Azure AI Search With Azure AI Search, the Palette Generator can understand the nuance of color language. Instead of relying solely on keyword searches that might miss the complexity of words like “vibrant” or “muted,” Pantone’s team decided to use a vectorized index for more accurate palette results. Using the built-in vectorization capability of Azure AI Search, the team converted their color knowledge base—including text-based color psychology and trend articles—into numerical embeddings. “Overall, vector search gave us better results because it could understand the intent of the prompt, not just the words,“ says Risteski. “If someone types, ‘Show me colors that feel serene and oceanic,’ the system understands intent. It finds the right references across our color psychology and trend archives and delivers them instantly.” The team also found ways to reduce latency as they evolved their proof of concept. Initially, they encountered slow inference times and performance lags when retrieving search results. By switching from GPT-4.1 to GPT-5, latency improved. And using Azure AI Search to manage ranking and filtering results helped reduce the number of calls to the large language model (LLM). “With Azure, we just get the articles, put them in a bucket, and say ‘index it now,’ says Risteski. “It takes one or two minutes—and that’s it. The results are so much better than traditional search.” Moving from inspiration to palettes faster The Palette Generator has transformed how designers and color enthusiasts interact with Pantone’s expertise. What once took weeks of research and review can now be done in seconds. “Typically, if someone wanted to develop a palette for a product launch, it might take many months of research,” says Jotshi. “Now, they can type one sentence to describe their inspiration then immediately find Pantone-backed insight and options. Human curation will still be hugely important, but a strong set of starting options can significantly accelerate the palette development process.” Expanding the palette: The next phase for Pantone’s design agent Rapidly launching the Palette Generator in beta has redefined what the Pantone engineering team thought was possible. “We’re a small development team, but with Azure we built an enterprise-grade AI system in a matter of weeks,” says Risteski. “That’s a huge win for us.” Next up, the team plans to migrate the entire orchestration layer to Azure Functions, moving to a fully scalable, serverless deployment. This will allow Pantone to run its agents more efficiently, handle variable workloads automatically, and integrate seamlessly with other Azure products such as Microsoft Foundry and Azure Cosmos DB. At the same time, Pantone plans to expand its multi-agent system to include new specialized agents, including one focused on palette harmony and another focused on trend prediction.Reimagining Telco with Microsoft: AI, TM Forum ODA, and Developer Innovation

Microsoft Thought Leadership Sessions CASE STUDY: Connected Intelligence: multiplying AI value across the enterprise 📅Sep 10 1:30pm CDT Peter Huang, Senior Director, Technology, Network Data and AI T-Mobile Andres Gil, Industry Advisor/Business Developer, Telco, Media and Gaming Industry Microsoft CASE STUDY: From hype to impact: operationalizing AI in telco with TM Forum’s ODA and Open APIs 📅Sep 11 1:30pm CDT Puja Athale, Director - Telco Global Azure AI Lead Microsoft Connected Intelligence & Azure AI Foundry: Scaling AI Across the Telco Enterprise T-Mobile and Microsoft are spotlighting a transformative approach to enterprise AI: Connected Intelligence. The joint session explores how telcos can break down silos and unlock the full potential of AI by enabling strategic collaboration across systems, teams, and technologies. The core challenge they address is clear: AI in isolation cannot answer even the simplest customer questions. Whether it's billing, device performance, or network coverage, fragmented systems lead to blind spots, duplication, and poor customer outcomes. To overcome this, they propose a unified framework that blends technology and culture—because tech alone doesn’t scale, and culture alone doesn’t transform. Azure AI Foundry: The Engine Behind Connected Intelligence At the heart of this vision is Microsoft’s Azure AI Foundry, a shared AI platform designed to scale intelligence across the enterprise and a core component of Microsoft’s recently announced Network Operations Agent Framework. Connected Intelligence integrates: Agent Frameworks and Agent Catalogs for modular AI deployment Hundreds of TBs of daily data from network switches, device logs, and location records Enterprise-grade orchestration and data governance AI/ML models aligned with customer-level time series events This architecture enables reuse, speed, and alignment across people, organizations, and systems—turning data into actionable intelligence. Model Context Protocol (MCP): AI-to-AI Collaboration A standout innovation is the Model Context Protocol (MCP), which goes beyond traditional APIs. While APIs connect systems through data, MCP connects intelligence through context. It allows AI agents to dynamically discover and chain APIs without custom coding, enabling real-time collaboration across network operations, device management, and deployment workflows. By integrating MCP into the API fabric, Microsoft is laying the groundwork for agentic AI—where intelligent systems can autonomously interact, adapt, and scale across the telco ecosystem. From Hype to Impact: Operationalizing AI in Telco with TM Forum’s ODA and Open APIs The telecom industry is moving from hype to impact by operationalizing AI through TM Forum’s Open Digital Architecture (ODA) and Open APIs.

Microsoft’s collaboration with TM Forum is enabling telcos to modernize OSS/BSS systems using the ODA Canvas—a modular, cloud-native execution environment orchestrated with AI and powered by Microsoft Azure. This architecture supports plug-and-play integration of differentiated services, reduces integration costs by over 30%, and boosts developer productivity by more than 40% with GitHub Copilot. Learn how leading telcos like Telstra are scaling AI solutions such as “One Sentence Summary” and “Ask Telstra” across their contact centers and retail teams. These solutions, built on Azure AI Foundry, have delivered measurable impact: 90% of employees reported time savings and increased effectiveness, with a 20% reduction in follow-up contacts. Telstra’s success is underpinned by a modernized data ecosystem and strong governance frameworks that ensure ethical and secure AI deployment. From Chaos to Clarity with Observability Despite advances in operational tooling, fragmented observability remains a persistent challenge. Vendors often capture telemetry in incompatible formats, forcing operations teams to rely on improvised log aggregators and custom parsers that drive up costs and hinder rapid incident resolution. Microsoft’s latest contribution to the Open Digital Architecture (ODA) initiative directly tackles this issue with the ODA Observability Operator, now available as open source on GitHub. By enforcing a standardized logging contract, integrating seamlessly with Azure Monitor, and surfacing health metrics through TM Forum nonfunctional APIs, the operator streamlines telemetry across systems. Early trials have shown promising results—carriers significantly reduced the time needed to detect billing anomalies, enabling teams to shift from reactive troubleshooting to proactive optimization.

Developing applications that implement TM Forum (TMF) Open APIs can be greatly accelerated with the help of GitHub Copilot, an AI-based coding assistant. By combining Copilot’s code-generation capabilities with TMF’s standardized API specifications, developers can speed up coding while adhering to industry standards. In this blog post, we’ll walk through how to set up a project with GitHub Copilot to write TMF Open API-based applications, including prerequisites, configuration steps, an example workflow for building an API, best practices, and additional tips. Introduction: GitHub Copilot and TM Forum Open APIs GitHub Copilot is an AI-powered coding assistant developed by GitHub and OpenAI. It integrates with popular editors (VS Code, Visual Studio, JetBrains IDEs, etc.) and uses advanced language models to autocomplete code and even generate entire functions based on context and natural language prompts. For example, Copilot can turn a comment like “// fetch customer by ID” into a code snippet that implements that logic. It was first introduced in 2021 and is available via subscription for developers and enterprises. Copilot has the ability to interpret the code and comments in your current file and suggest code that fits, essentially acting as an AI pair programmer. TMF Open APIs refers to a set of standardized REST APIs for telecom and digital service providers. The APIs are designed to enable seamless connectivity and interoperability across complex service ecosystems. In practice, the TMF Open API program has defined over 100 RESTful interface specifications covering various domains (such as customer management, product catalog, billing, etc.). These APIs share a common design guideline (TMF630) and data model, ensuring that services can be managed end-to-end in a consistent way. Why use GitHub Copilot for TMF Open API development? Integrating Copilot with TMF Open API streamlines telecom app development. Copilot helps generate boilerplate code, suggests API handling snippets, and provides usage examples, all in line with TMF specs. For developers building services like Customer Management or Product Catalog, Copilot autocompletes endpoints, models, and business logic based on learned standards, maintaining TMF consistency. Developers review and edit outputs, but Copilot eases repetitive tasks. The following sections will guide you on setup and practical use with TMF Open API. "With GitHub Copilot, TM Forum members can accelerate API development — reducing boilerplate coding, improving consistency with our Open API standards, and freeing developers to focus on innovation rather than routine tasks. We’d love to hear from members already experimenting with Copilot — your experiences, lessons, and best practices will help shape how we embed AI-assisted coding into the wider TM Forum Open API community." - Ian Holloway, Chief Architect, TM Forum Prerequisites for Setting Up the Project Before configuring GitHub Copilot in your project, make sure you have the following prerequisites in place: GitHub Copilot Access: You will need an active GitHub Copilot subscription or trial linked to your GitHub account. Copilot is a paid service (with a free trial for new users), so ensure your account is signed up for Copilot access. If you haven’t done this, go to the https://github.com/features/copilot and activate your subscription or trial. Supported IDE or Code Editor: Copilot works with several development environments. For the best experience, use a supported editor such as Visual Studio Code, Visual Studio 2022, Neovim, or JetBrains IDEs (like IntelliJ, PyCharm, etc) GitHub Account: Obviously, you need a GitHub account to use Copilot (since you must sign in to authorize the Copilot plugin). Ensure you have your GitHub credentials handy. Programming Language Environment: Set up the programming language/framework you plan to use for your TMF Open API application. Copilot supports a wide range of languages, including JavaScript/TypeScript, Python, Java, C#, etc., so choose one that suits your project. TMF Open API Specification: Obtain the TMF Open API specifications or documentation for the APIs you plan to implement. TM Forum provides downloadable Open API (Swagger) specs for each API (for example, the Customer Management API, Product Catalog API, etc.). Basic Domain Knowledge: While not strictly required, it helps to have a basic understanding of the TMF Open API domain you're working with. For example, know what “Customer Management API” or “Product Catalog API” is supposed to do at a high level (reading the TMF user guide can help). This will make it easier to prompt Copilot effectively and to validate its suggestions. For more training, please refer to the TM Forum Education Programs. With these prerequisites met, you’re ready to configure GitHub Copilot in your development environment and integrate it into your project workflow. Step-by-Step Guide: Configuring GitHub Copilot in Your IDE Setting up GitHub Copilot for your project is a one-time process. Here is a step-by-step guide using Visual Studio Code as the example IDE: Step 1: Install the GitHub Copilot Extension. Open Visual Studio Code and navigate to the Extensions view (you can click the Extensions icon on the left toolbar or press Ctrl+Shift+X on Windows / Cmd+Shift+X on Mac). In the Extensions marketplace search bar, type “GitHub Copilot”. You should see the GitHub Copilot extension by GitHub. Click Install to add it to VS Code. This will download and enable the Copilot plugin in your editor. Step 2: Authenticate with GitHub. After installation, Copilot will prompt you to sign in to GitHub to authorize the extension. Click “Sign in with GitHub”. Log in with your GitHub credentials and grant permission to the Copilot extension. Step 3: Enable Copilot in your Workspace/Project. Now that Copilot is installed and linked to your account, you should ensure it’s enabled for your current project. In VS Code, open the command palette (Ctrl+Shift+P / Cmd+Shift+P) and type “Copilot”. Look for a command like “GitHub Copilot: Enable/Disable”. Make sure it’s enabled (it should be by default after installation). At this point, GitHub Copilot is fully configured in your development environment. The next step is to actually use it in developing a TMF Open API application. We will now walk through writing code with Copilot’s assistance, focusing on a TMF Open API use case. Writing TMF Open API Apps Using GitHub Copilot Now for the fun part – using GitHub Copilot to help write an application that implements a TMF Open API. In this section, we’ll provide a step-by-step example of how you might develop a simple service using a TMF Open API (say, a Customer Management API) with Copilot’s assistance. The principles can be applied to any TMF API or indeed any standard API. Scenario: Let’s assume we want to build a minimal Customer Management microservice that conforms to the TMF629 Customer Management API (version 5.0) – which manages customer records. We will implement a simple endpoint to retrieve customer information by ID, as defined in the TMF API spec. We’ll use Node.js with an Express framework for this example, but you could choose Python (FastAPI/Flask) or Java (Spring Boot) similarly. The emphasis is on how Copilot assists with the coding. Step 1: Referring to TMF Open API GitHub API specifications Before coding, ensure you have the TMF629 API specification open or accessible for reference. For example, the spec might say there’s a GET operation at /tmf-api/customerManagement/v5/customer/{id} for retrieving a customer, and defines a Customer data model. If you have the YAML/JSON file, open it in a VS Code tab – this provides Copilot with a bunch of context (resource paths, field names, etc.). Copilot can use this textual context to inform its suggestions. The spec files can be downloaded from below link (needs a TM Forum registration and login): Customer Management API REST API v5.0 Open API Directory (Link for all API specifications) Step 2: Set up the project scaffolding. Initialize a new Node.js project (e.g., run npm init -y for a Node project, and install Express by running npm install express). Then create a file index.js (or app.js). In that file, start with the basic Express server setup: const express = require('express'); const app = express(); app.use(express.json()); // Start server on port 3000 app.listen(3000, () => { console.log('TMF Customer API service is running on port 3000'); }); As you type the above, Copilot may autocomplete parts of it. For instance, after writing app.listen(3000, () => {, you might see it suggest a console.log line. It’s standard boilerplate, so nothing magical yet, but it confirms Copilot is active. Step 3: Implement an API endpoint using Copilot. Consider the TMF629 Customer Management API Customer Management API TMF629-v5.0 Now, according to the TMF specification, the GET Customer by ID endpoint should be something like: GET https://host:port/tmf-api/customerManagement/v5/customer/{customerId} -> returns customer details. Let’s write a handler for this. Start typing the Express route definition. For example: // GET customer by ID app.get('/tmf-api/customerManagement/v5/customer/:id', (req, res) => { // }); The moment you write the path string and arrow function, Copilot is likely to recognize this as a request handler and may suggest code inside. It has context from the route path (which is quite specific and likely uncommon except from the TMF spec) and the comment. Copilot might suggest something like: fetching the customer by ID from a database or returning a placeholder. Since we haven’t defined a database in this simple scenario, let’s see what it does. Often, for a new route, Copilot might guess you want to send a response. It could for example suggest: // ... inside the handler: const customerId = req.params.id; // TODO: fetch customer from database (this is a Copilot suggestion comment) res.status(200).json({ id: customerId, name: "Sample Customer" }); }); Of course, this is just an example of what Copilot might do. In practice Copilot may complete the code differently. The key is that Copilot can help stub out the logic. If it doesn’t automatically fill it, you can nudge it by writing a comment or function description inside the handler, such as: // Find customer by ID and return as JSON After writing that comment, pause and see if Copilot suggests a code block that finds a customer. If we had more context (like a Customer array or database connector imported), it might try to use it. For now, you can accept a basic implementation (like returning a dummy object as above). Accepting the suggestion, our route becomes: // GET customer by ID app.get('/tmf-api/customerManagement/v5/customer/:id', (req, res) => { const customerId = req.params.id; // For demo, return a dummy customer object res.json({ id: customerId, name: "John Doe", status: "ACTIVE" }); }); Here we assumed Copilot suggested returning an object with some fields. If the TMF spec defines fields for a Customer (e.g., name, status), and especially if the spec file is open in another tab, Copilot might use actual field names from the spec in its suggestion because it “saw” them in the YAML. This is a huge win: it helps ensure your code uses correct field names and structure as per the standard. For instance, if the spec says a Customer resource has id, name, status, Copilot might include those. Always verify against the spec, but it often aligns. You continue this way for other operations (PUT/PATCH to update a customer, etc.), each time leveraging Copilot to write the initial code which you then adjust. Copilot can also help with non-HTTP logic: for example, if you need a function to validate an email address, just write the function signature and a comment, and it will likely fill it in (because such patterns are common in its training). Step 5: Use Copilot for documentation and examples. Copilot can even assist in writing documentation-like content or tests for your API. For instance, you could create a README.md for your project. Step 6: Iterate and refine with Copilot Chat (if available). GitHub Copilot includes a Chat mode (Copilot Chat) in VS Code, which acts like an assistant you can converse with in natural language. If you have Copilot Chat enabled, you can ask it things like “How do I implement pagination in this API according to TMF guidelines?” or “Suggest improvements for error handling in my code”. The chat can analyze your code base and provide guidance or even write code snippets to apply. GitHub Copilot provides the capability to choose your own model (e.g. GPT-4.1, GPT-4o, GPT-5 or Claude 3.5 Sonnet, etc.). This provides additional flexibility to Telco developers building solutions on TM Forum (TMF) Open APIs. This flexibility means developers aren’t limited to one generic AI assistant – they can select the model best suited to each coding task, whether for rapid code suggestions or complex problem-solving. Step 7: Test and validate against the TMF spec. Once you have your endpoints coded with Copilot’s help, it’s crucial to test them against the TMF specification to ensure correctness. Use tools like Postman or curl to call your API endpoints. For instance, GET http://localhost:3000/tmf-api/customerManagement/v5/customer/123 should return either a dummy customer (if using in-memory data as above) or a 404 if not found, as per spec expectations. Compare response structures to the TMF API definition. If something is missing or named incorrectly (say Copilot used customerName but spec expects name), adjust your code accordingly. Copilot is not guaranteed to produce 100% correct or updated spec implementations – it provides a helpful draft, but you are responsible for aligning it exactly with TMF’s definitions. During testing, you might encounter bugs or mismatches. This is another point where Copilot can assist: if you get an error or exception, you can paste it into Copilot Chat or as a comment and prompt Copilot to help fix it. For example, if you see your server crashes on a null reference, you can write a comment // Copilot: fix null reference in customer lookup near the code, and it might suggest a null-check. Best Practices and Tips for Using Copilot with TMF Open APIs To use GitHub Copilot efficiently for TMF Open API development, follow these key practices: Apply Copilot for Repetitive Tasks: When implementing endpoints with similar logic (e.g., CRUD operations), use an initial example as a template. Copilot will recognise patterns and help adapt code for new entities. Prompt Clearly and Iterate: Refine prompts to get better suggestions; add specifics in comments for improved results. If output isn't right, adjust your instructions for more detail. Verify Against TMF Standards: Copilot's knowledge may not reflect the latest TMF specs. Double-check generated code against official documentation and provide context from newer specs when necessary. Incorporate Security and Quality Checks: Always validate Copilot’s code for security and proper input handling. Use Copilot Chat for advice on improving validation and ensure you meet industry standards (e.g., OAuth). Learn From Suggestions: Use Copilot to expand your skills, especially if you're new to a language or framework, but confirm that its examples suit your use case. Don’t Over Rely on Automation: Copilot is best for boilerplate and common patterns; customise business logic and architecture-specific code yourself. Keep Relevant Files Open: Copilot works best with focused context. Close unrelated files to improve suggestion quality. Update Copilot Regularly: Keep your extension up-to-date and try different AI models for improved performance. Following these principles will help make Copilot a productive partner in TMF Open API projects, offering speed while maintaining adherence to standards.
