You should convey important information in multiple modes, not just color. If you are still required to do so, at the very least you should complement that info with other modes, like symbols, if the user requested differentiation without color.
Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

Since iOS 14, you can get a human readable localised name for a UIColor, with a very useful property called accessibilityName, that you can use in accessibility attributes like labels or values. How cool is that? https://developer.apple.com/documentation/uikit/uicolor/accessibilityname
