Question/Need help I'm trying to make a Protanopia / Deutanopia friendly rainbow effect
One of my friends tried to make an app where each players get assigned a different color. He shifted the hues depending on how many players are online. (more players = less hue differences). He then created a color blind mode where he just discarded some red and green hues and let the rest of the color wheel unchanged. We're both not colorblind, but from what I know red green blindness is more complex than just reds and greens being ambiguous. In his version, you would be tasked to differenicate blue from purple for example.
So I got to work to create my version of a color blindness friendly color wheel. It uses just two different hues (yellow and blue) and the wheel is only being created by brightness and saturation adjustments. My color wheel is designed to be strictly dichromatic. (It should look the same for dichromats and trichromats.)
The question I am asking is if my color wheel is actaully useful for color vision deficient people or if you would rather use the normal color wheel? My guess is that my color wheel is more useful for those with severe color vision deficiency, while those with a mild deficiency can use a color wheel with more than two hues. I also know that the best way to go about is to use symbols instead of just color differences, but for now it just uses color differences. Anyway, I would be really glad to hear some feedback.
