SharePoint 2019 on-premises custom theme using a PowerShell script
I am on SharePoint 2019 on-premises with May 2023 CU. I see Gear, Change the Look. Current theme. I want to set COMPANYTHEMEHERE as the theme. I have done so in SharePoint Online however I have to use PNP and I do NOT have that on-premises.
I go to help on the SharePoint 2019 on-premises site and it takes me to - SharePoint site theming.
I have gone to the Theme Generator Tool - https://aka.ms/themedesigner and I have a basic theme. I am only changing the color of our site from SharePoint teal to our company branded color.
I go to the SharePoint site theming: PowerShell cmdlets:
THIS is taking me to information about SharePoint ONLINE and NOT on-premises, which in SharePoint 2019 I am on-premises!
What am I missing as I would like for a way to update the color of the theme on-premises.
Matthew Carter , Did you find a solution for this? I have a same issue.
I do not believe it is possible to deploy a custom theme to on premise using PowerShell. What I have done in the past is to design my theme using the SharePoint Color Palette Tool. Then I modify the default palette to create my own. Thhis tool is no longer available from Microsoft, but can be found in a Reddit thread here: https://www.reddit.com/r/sharepoint/comments/129els4/anyone_have_the_old_sharepoint_color_palette_tool/?rdt=53416 (If you cannot download it, you might have to simply download and edit an existing .spcolor file from the Themes folder in a text editor.) Then I upload it to the Themes folder under Site Settings. Then I go through the classic Change the Look options to select the color scheme I have created.
