contrast isn't really just an accessibility niche thing. It helps way more people than you'd think. There are billions of people with some kind of vision impairment, and contrast sensitivity drops with age anyway. Add players on a dim laptop, a cheap monitor or a phone, and the small text in those cells gets hard to read for a lot of people. So I'd see it less as "accessibility design" and more as just making the panel readable. The WCAG gives good guidance here.
the latest update actually added a colourblind setting, right next to the UI setting. So that part is already covered.
We also threw around ideas with more colours then 3. Blue would be an awesome colour same as purple.
