    I have a red/green colour deficiency.
    I WAS planning on joining the navy when I turned 17, or the Coast Guard as an alternative.

    When I tried to apply I found out I was colour blind and I couldn't do either of those!

    Anyone else colourblind?

    That's a bummer guy. I guess it is kinda important to see color. I mean, you don't wanna cut the wrong wire and all. ;)

    As far as I know, taking the tests, I am not.
    Just curious though... how do you know when the traffic light is red or green? I know you can prolly tell if it is yellow (duh) but I have heard that green is like brown to someone who is color blind. Or do you just not see them at all?

    The way the signals are designed is supposed to make it somewhat easier for those who are color blind (or so I have heard).

    I'm deuteranopic.

    Aren't street lights in the same order basically everywhere?

    I can actually see the green/red traffic light just fine.
    It doesn't affect me that much, I actually find blues/purples
    harder to tell apart than red and green.

    I remember reading somewhere that the shades of red and green in traffic lights
    are supposed to be easy to distinguish for most.

    Color blind here as well, mainly red/green but different shades of most colors throw me.
    For me the green light is white.

    Ah, I see.
    I read that too.
    I also didn't consider that green is likely to show up if you can not see red/green color (it will just be a bright light) and that the position of the lights is important. Red is at the top, yellow is in the middle, green at the bottom.

    In the most common type of red-green deficiency, boys can see primary colors just fine, but have trouble with pale shades of red and green. (They both look tan or brown.) So most aren't aware of it until they take an Ishihara test.

    For me, it's odd. All of the common information says that red-green color deficiency is caused by an x-linked mutation. However, I failed the Ishihara tests in high school, but by the time I got out of college, I passed them just fine.

    I suspect it was X-linked all right... linked to my mother's awful excuse for cooking. I basically didn't get any significant protein or vitamin sources until I started eating in the college dorms. A variety of small studies have shown that diet can affect color vision. I haven't seen any conclusive reviews on the topic though.

    If your diet is short on fruits and vegetables, you might consider improving it a bit. Then try the Ishihara test again after a year or two.

    Are you color-blind? You should be able to see numbers inside the circles. If you can’t then you may be color- blind. Test yourself below.

    Color blindness is almost always an inherited condition although males are more likely than females to experience it.

    I style people at work and I'm always surprised how many guys that come to me with some degree of color blindness. My own eyes developed differently from each other and I see a very different range of colors with each one. I can only really tell the difference when I close one eye. Everything is brighter with the left, especially yellows and reds. The right sees bluer and less intense. Together they must work pretty damned well, because my coworkers, and more importantly clients, tell me my color perception is pretty dead on.

    Six needs a little bit concentration, otherwise rest was easy.

    Just noticed it now, but you spell colour like it should be. When I first came to states couldn't think of any reason why spell check always marked it as incorrect. Until I realized that I need to update my spellings for a couple of words like color.

    Yeah, i know im colour blind, i cant make out any of these numbers.
    In HS, the Red marker blended with the white board making it impossible for me to read anything since i couldnt see a thing.

    From what I understand, these four images simulate how color blindness looks:

    Color blindness is more common in men and it’s not very unusual. Take a look at this link:
