Graphical Indicators Image Colour Changed with Project Online

Curious if anyone else has picked up the colour change in the graphical indicators icons between Project Professional and Project Online?

I've been using Microsoft Project Professional Desktop Client for many many years, but recently started at a new organisation and we're using Project Online Desktop Client. For the last decade or more in Project Professional I've been using graphical indicators to flag Gold, Silver and Bronze milestones, bulbs for decisions, flags for dependencies etc. you get the gist. I'm a visual being, and icons are a great way for me to scan my large and complex master and program schedules 🙂 I've noticed that the colours of the icons in graphical indicators have changed slightly (not for the better) between the two project versions and I'm desperate to get what I've been doing for over an eternity back. I'll explain what I mean in pictures.

Project Professional original icon image colours being used:

You can see it's colour icon 11 which has a much browner tone.

Project Online icon image colour for icon 11:

You can see here it's very blush, red almost, not a good match for my bronze milestones.

Need to figure out how I can either adjust the colours (which I don't think I can do), or figure out how / why these colours look different now, as I want to roll out my usual templates to the Enterprise but they look different. Side note - why have the icons all got blurred edges now, another design change not for the better IMO.

Anyone with any ideas for me, please chime in.

Many thanks! 🙂
