Rainbow Faces Custom Feature

I have found Rainbow Faces from Smart Bench Software to be a great Custom Feature!
Not only do kids love the pretty parts, but it also helps with understanding of drawings and how features show up in different views.
Thanks @Caden_Armstrong!

Very cool. I missed this. I've often wished for more diagnostic shader options for Onshape. This seems like it covers the random one well. Thanks!

If I could make a request, it would be to try to make the random colors more distinct. I'm sure making every border between different colors high contrast would be a very challenging thing to do algorithmically (kinda like in 2D the 4-color map theorem). At least according to a quick discussion with ChatGPT it sounds like 7 colors for an object which is topologically a sphere, but each hole you add (to make it into a torus) adds a color (a single hole means 8 colors, two holes 9 colors, etc).
It would help if the palette doesn't include any colors which are close in LAB or HSV or even RGB.
Here's the beginning of my research if it's of any help: https://chatgpt.com/share/682b7ce8-09b4-8010-bdf1-bb47ea47458c
