This is a question I receive a lot, and the answer is... well, it's complicated. Officially, I have severe Deuteranopia, which encompasses red-green colorblindness, but that description fails to describe some of the other colors I have issues with (such as yellow-green, pink-blue, blue-green) so I also tend to say I have mild Tritanopia, which also encompasses blue-yellow colors (though it should be noted this is not an official diagnosis, unlike the Deuteranopia).

To be clear, I don't mean to pretend that I am the end-all-be-all speaker for colorblind people around the world, but the reason I make such a big deal about these things is because first and foremost: it PISSES me off when things are inaccessible because of careless oversights. You'd be surprised at how easy it is to fix a lot of these issues, but for some reason, some developers just continue to FLOUNDER when it comes to these things.

Most notable example of this is in Destiny 2, where they allegedly made a change to enemy shields for the sake of "accessibility", but in actuality, it just made things worse! It just makes my blood boil to make my enjoyment of things be impeded by something I can't control, and I want to yell about it even if it makes me seem like a jackass sometimes.

This was a question I received on my Steam Review of Poco from a very, very inane individual.

Well, why don't you just flip the question to any other disability. Why don't deaf people simply use hearing aids for games that have pure audio cues? Why don't mute people use TTS for games that require communication but don't have text chat? Why don't amputees simply use custom controllers?

The answer is: they could, but it shouldn't be expected of them, ESPECIALLY when some people can't afford these tools. For example, sure, I could always use my EnChroma glasses, but have you seen how much those things cost? I'm fortunate enough that I could afford them, but I'm not expecting everyone to drop the money for it.

Oh, and another thing, is that SOMETIMES, these "tools" AREN'T EVEN APPLICABLE. 

I know that a lot of people were fooled by Logan Paul peddling EnChroma glasses as a "miracle cure" to colorblindness, but what I must stress is that the glasses are NOT that. What they do is help you "distinguish" colors from one another, but not necessarily "identify" them, so to speak. Helpful for games like Puyo Puyo where you can just associate the pieces with "that" color and "this" color, but not for games like Poco where you're looking for a specific color you're not even sure what it looks like.
