We can show that the functions of color perception are the same (or aren't), but subjective experience IS NOT a function and there is no way to observe it, hence no way to show anything about it.
There are different forms of color-blindness from partial to total. Such can change how people perceive much information because much information is color-coded.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
