Yes yes, texture pack mods are stupid easy and everyone's making them, but I noticed there isn't one made specifically for colorblind people.
Now I have no experience making things for colorblind people, but I did find an app that showed me what certain colors looked like for people who have Protanopia, Deuteranopia, and Tritanopia. I tried to pick colors that were similar to Caro's 4-color deck but were also easy to tell apart no matter which colorblind type you suffer from (so long as you're not monochromatic).
So, here ya go. It's definitely based off of these two mods.

Anyway, below is a picture of what colors I chose on the left, and then in order: Protanopia, Deuteranopia, and Tritanopia (according to the app I was using).
