My father is red-green color blind. And frankly speaking, until he told me, I never noticed that. And he even got a driver's license in the old days (I mean 198X).

While I'm lucky enough to have full color vision, I find myself can't imagine how color blind see the world. Sometimes I wondering if I'm color blind but just don't know that. (Several tests on the internet said I'm perfectly fine)

The thing is, how I can tell I'm color blind if I don't know what color I don't know? When talking about the flavor, I found my father and I are not sensitive to the taste of sour, while my mother is. For the same dishes, my mother thinks it is unacceptable sour, while my father and I think it's not sour enough. If I can't taste the sourness at all, how do I know I have that defect?

I'd rather not think this deep hole of a thing of philosophy. I guess it's a philosophy thing. Surely it's not literature.

I guess I lost the point during typing. When watching those videos I was thinking about different things but now I forget.

Now I'm wondering if I got ADHD.

@skyblond

you dont know what you dont know- until someone tells you about it. then you know what you didnt know- but will still never know what you dont know- only that that you previously did not.

its possible there are colors that most people cannot see and are not aware of.

I can't see uv. 😭

@Humpleupagus @lucifargundam

Talking about that, I once read a passage said birds can see RGB along with UV. Their world is much more colorful than humans.

I wonder what that means to me. The RGB vision I have is colorful enough for me, I don't know if my brain can handle those extra color space.

Also, unlike scifi, human brains can imagin something like space travel or time travel, I noticed that my brain (as it can represent the average human brain, I guess?) has difficulties imagining senses. The most obvious one is the taste, when I can't reproduce what others claim, with the same dished.

While general senses seem to be inate for most people, that minutia is "acquired." Native asians can't properly pronounce certain English sounds because they literally can't hear them as a result of those sound not existing in their native tongue, and therfore, not being exposed to them as a child. A trained musician hears music differently than a non-musician. Etc.
