Would it be possible to generate ones that _would_ work for specific kinds of colorblindness? Or is the entire concept doomed due to the specific way(s) that colorblind eyes are messed up?
I suspect, however, that those of us with deuteranomaly probably see a different blue-green than normal-sighted folks due to the bent color cones.
The real question is, what about the folks with Deuteranopia (no working green cones at all)?
Deuteranomaly, though, is still probably the best place to start since that's the big one that affects (some say) up to 10% of all males. Every other form of colorblindness affects a much slimmer percentage of the population.
I fail on the first page of the Ishihara (?) test. When using those colorblindness filters in photoshop/-like apps, the protanopia and deuteranopia filters do very little for me. No 'real' diagnosis. I can see red and green though, but the shape needs to be big, and the color should be quite saturated. Reading resistors is really hard.
