I found out that i'm red-green colourblind about 2 years ago, and it doesn't really affect me that much
Well, sometimes i can't tell between similar colours but that's about it
It was surprising when i first found out though




If you can't see the numbers, well you're colourblind

Yup...put me on the list. Lot of males are color blind and most don't even know it. It's a male trait.

It is possible for women to be colour blind, its just very rare. I personally am not.

What the heck do those dots mean?

Yep, I'm red-green colour blind too. Most people I tell start testing me straightaway. They seem to think that I should see black as bright yellow and blue as pink.

i have a question, i dont know much about colorblindness.

is colorblind an inability to differentiate between two colors, like above, or is it also inability to perceive some colors correctly or not at all?

i would guess there are many different type?

Monochromacy is very rare. Most people who are colorblind cannot differentiate between certain colors, or have much trouble doing so. For the record, I have perfect color vision.

curse you jdimitri.. I had almost forgotten this certain handicap until you decided to remind me >____<"

I seem to be fine.

well I'm not in ... I can see the numbers in there (although the one at the bottom is easier to see then the one at the top)

I'm.. sorry?

Just saw little miss sunshine and just randomly thought about it
Watch it btw, one of the best movies ever

I remember that I used to go hours on end to "see" the difference. After awhile, I do see the picture in the dots as normal people should. It just takes awhile.

More to do with my brain than my eyes though, as I judge shapes by the difference in hues- eventually I see it. I doubt that it will even help a little. Now that I look , I can see it after a few minutes (guess I'm improving). Though I'm "blinded" by ambition, and these are fruitless attempts at nothing more than time wasting denial, I will still do it from now on again. They say practice makes perfect, but we'll see. Even If my "cones" are non functional, Im pretty sure there are backup methods, maybe the brain just needs some conditioning, or there is some physiological connection I can make....

It somehow seems like audio too.. You don't see the difference until Its missing. When it's there with other things going on, you don't notice it. When you remove the thing you're looking for then it is easy. I've never know I was colorblind until I actually got an eye exam at age 16. Never had any trouble with lights, identifying colors, or anything. I guess if no one told us mild protanopics and deuteranopics anything about color blindness or those evil evil dot exams we would still be pretty happy. Ignorance is bliss...

Last I heard approximately 10% of all males have some form of color deficiency (why in design you should never use color exclusively in presenting options). I do. Interesting though when I was going through art school (and painting classes most semesters) I started passing many more color blind tests. That was quite surprising. Then my perception got lazy or whatever again. I can't read the above.

As mentioned monochromatic viewing is very rare (but great WWII map viewers!), but I'd have no idea how you would test "perceiving colors correctly." My red is more correct than your red. As far as I know it's always multi-color relationships tested.

Ishihara charts (those dots that are supposed to form a number or figure) are out of favor as a test for color- blindness, as a person with a below-normal ability of color vision can learn and memorise the patterns. Nowadays the favored test is color matching: the subject given a piece of wool yarn of a specific color, and is asked to choose from a set of yarns the one that match.

I've got red-green colorblindness (or "color discrimination deficiency" if you don't want to confuse people who don't understand that it's not really colorblindness). I've gotten better at dealing with it over the years. When I was really little I thought that healthy grass was orange, and that people just called it green because most things in nature were green. Now I only have trouble with a few things, like telling very light greens from yellow and dark blues from purple.

The last time it was actually a problem was a few years ago when my hockey team in our red jerseys was playing a team in brown jerseys and we both forgot to bring our whites.

No, I am not!
I can clearly see two numbers, the first one are one digit and the second one are two digits.
