I went in for a medical exam last week and was surprised to find that I could not pass the colorblind test!!! I've never had this problem before that I can remember, and perhaps I haven't taken too many colorblind tests. I don't know if one can "become" colorblind later in life...

After some internet research, I was a bit shocked to discover that being colorblind doesn't mean you see things in black-and-white, but that you don't distinguish colors as easily as a normal-sighted person. Something like 5-10% of males are color-blind to some extent, but most (like myself) have no idea until they take a colorblind test. I have a form of red-green colorblindness, but I see all colors fine and have no problem distinguishing colors on a stoplight (for example). I find it interesting that even though I thought my vision was normal, I don't see things quite the same as the other 90-95% of people out there.

Has anyone else been surprised to learn you are a bit colorblind?

I do think I heard about a condition like that. It's somehow linked to depression, I think. Confused

Yeah, I've known that I was colorblind for a long time. People don't understand what it means when I tell them that I'm colorblind. It means that we see the world in a more boring less vibrant more bland way than regular people do. I too have red-green color blindness. It's easy for anyone to find out if they're color blind or not. Just google for 'color blind test' or something like that. I dread doing the look-for-the-number-in-the-colored-bubbles test.

I had a friend in university who was quite colorblind. We used to play a lot of puyo-puyo, which is a competitive, puzzle video game where you match falling beans according to color. He was absolutely abysmal at it, laughably terrible. We had a great deal of fun mocking him.

I'm red-green colorblind. As this wasn't enough, I'm a lefty and was born prematurely. What are the odds at that? 0.0001%? Razz

Koreans call many kinds of dark blue: black .. and kinds of red: orange or brown .... cultural concepts overlap but vary at the edges

No worries, in Korea they use the exact same colorblindness test as that website.

I too noticed people disagreeing with what color I see, especially people of other races like Koreans; not to be racist or hateful. I really learned more about this in my teaching and know when it's English speaking error and visual perspective error. Since I was young, I always wondered if each individual sees and perceives the world in different color, light, and dept. I think my early childhood curiosity about this is confirmed to be true. We do all indeed see and perceive the same colorful world differently around us.

I've taken color blind tests many times and know I see color just find. It's just the damned having to wear glasses part due to imperfect eyeballs, a common problem all races and people all over have. Some people see mostly browns and weak green hues while most see 16.8 million or more vivid colors with unlimited amounts of color at a time. Others see pink as red, a common error, others seen greens as browns, and a few others see the world in total monochromatic. It's said cats all have monochromatic vision. Vision is quite an interesting thing.

I do think exactly the same way. I even believe, some people might have totally reversed color system of mine. But it doesnt bother right?

Something off the topic that occurred to me

Children are closer to supernature, when I was young, I could looked into the sky for hours thinking and listening to voice from the outer space. I also had better comprehension of previous life, future life and death...

Some women can actually have eye receptors for four primary colors, instead of three (or two) like most people.

http://ray.tomes.biz/b2/index.php/a/2007/06/21/p147

The title is just a fancy way of saying that some women seem to have four colour receptors in their eyes rather than the usual three. Actually some people also have a different set of three and this was known for some time before the discovery that quite a few women see extra colours than the rest of the population. Of course some men are missing a receptor and have only two and as a result are called colour blind. Compared to tetrachromats we are all colour blind.

im colourblind. You inherit it from your mother - it affects males only in a family. Your grandad probably had it.

It was hard but I figured out the words. Then I saw the same thing in the page title and URL. Laughing
