I guess no. I know a few colorblind people and I’m passingly familiar with how people cope with it. There’s also no “white/nearly white” colorblindness. Those two colors differ in value which even a totally colorblind person could tell apart.
Also ratcha works digital and photoshop/sai/gimp show you the rgb density under the pointer. A colorblind person would probably also use layers and filters to better see the contrasts they’re insensitive to.
What I think is going on here is it’s a laptop or a shitty cintiq ripoff that has such bad off axis performance that they are barely able to see the colors they’re working with. Also I’m pretty sure ratcha streams with music playing and while chatting with fans, a very distracting environment.
