I was getting my eyes tested this week and it turns out I'm colour blind, I never knew this growing up, I find it strange that this went 21 years without being noticed. I'm pretty lucky in that it doesn't affect what I'm studying to be or my current part time job. Again I just find it weird that it went this long without being noticed, anyone else I know who has it has known since they were a kid.

What kind of color blindness? I have a friend who is, but you can't tell with him. He has deuteranomaly. He can see red in some contexts and in some not. Green he can usually see but not always. This did not prevent him from being an artist. Picking red berries from a green tree, forget it. He totally failed the color vision test.

Especially mild colorblind types seem to go unnoticed until tested. Not sure what you have, but if it's not that severe I guess you never gotten into any arguments what color something is. And without that, you couldn't know others see things in a different way.

She didn't really go into much detail on it, mostly because I was busy that day and didn't ask too much, but it was the red-green tests I couldn't get

Ah so you're red/green color blind. I am too! I went years without knowing until I was about 18. It doesn't really disturb anything. I still see green and red, they are just "my" green and red.

Possibly the best question I've been asked is "What on earth is Christmas even like for you?"

(also just thought I'd share my love for your icon haha)

if everyone around a baby/child always calls the colour of a strawberry pea green the child will grow up calling it pea green even though they actually are seeing red. so no matter what colour your eyes are seeing you will call it the colour you have been taught that colour is. so three people may all see banana as a different colour in their eyes, but they will all still call that particular colour yellow because that is what they were taught the colour of a banana is. only a specific test will identify colour blindness. so it is extremely common for it to go undiagnosed for many years

My friend never understood why he couldn't find berries to pick with his mom (red berries, green leaves) and claimed he didn't see the berries. For him they had the same color. It was kind of hinting that he had an issue and with more similar experiences they realized something was different. But that is sort of by chance. All families don't go pick berries.

I'm unsure what he really saw. He could properly name red and green in many situations but in some he didn't see a difference.

He could probably see my siggy pictures as green and red. But if you would make a big pattern made of those same two colors suddenly he can't tell them apart. I have no idea how that works.

my brother found out he was coulor blind in his 20's when he joined the army.

From what I understand it is the most common versions that go unnoticed the longest.

People are trichromats even if it has been speculated there are some with ultra high color perception which might have yet another set of color vision cells.

Deuteranomaly is when you are still a trichromat and you can see red and green as different colors, but some of the cones don't work optimally and makes you mildly red-green color blind.

You can also be a true dichromat and have deuteranopia which makes you see no difference between red and green part from a slight shift and intensity.

Oddly enough my friend saw colors I did not see and I have perfect color vision. Something I saw as grey, he saw as purple. But neon green (like a strong yellowish color with a green tint) he saw as pure yellow. He could not see any green in it at all.

Dichromats have been known to see more shades of green than others. It is quite interesting I think.

A lot of mammals are dichromats and horses seem to be able to tell the difference between different greens that we don't. They don't have a problem spotting a green fence in green grass while it might go unnoticed to us. But then again, their food is green so I guess they have to see it well. But still humans feel superior because we have "better" color vision as trichromats.... Hubris, LOL.

Knowingly at least, I have not come across any colorblind people that did not have one of those two types.

Hmmmm according to those I have total color blindness, again I never got a chance to go into it with her, I'll ask more about it when I collect my new glasses next week

Yikes. That is kind of rare. And makes me wonder how you tell colors apart. And the deep side of things, how would it be to be inside someone elses head?

Remember it's on a screen though. This test I believe should really be done in print. Some screens dilute colors quite a bit.

Still came up red and green. I can see red and green, it's the tones that I seem to get a bit botched up.
