So you propose that colorblind people should make their OS turn all images, photographs and video into false color not correlating with reality because in some specific contexts color is used symbolically and it's important to distinguish between two colors? One option that might work would be a special drawing mode implemented in the OS graphics stack that did some mapping depending on what's configured in the accessibility settings; then applications could request that in the rare cases where it's important.

As a partially colorblind person (albeit easily capable of telling red from green here), while of course such a mode should not be required for programming, I wouldn't mind using it in general. The EnChroma glasses try to do this in real life, but they're expensive and only work in bright sunlight; if I can at least get the same for photos just by downloading something, it sounds interesting. (And probably already exists, so I should do some Googling.)
