Are you color blind?

[MuniAddict]

I know it's more common for males than females. I'm red-green color blind and as a kid I took a standard visual test that they still use today to determine whether or not you are color blind. In the test below there are six circles comprised of colored dots. Those who are not color blind will quickly see numbers in every circle. those who are Red-green color blind (me) will see only two numbers; 25 & 56.

I'm not color blind (I figured as much).

I could see the 25 in the first circle but that was it.
I'm a graphic designer.

I really like monochromatic stuff.

I am a little bit.
Sometimes I think green is blue.

Here are some statistics:

Color blindness affects a significant number of people, although exact proportions vary among groups. In Australia, for example, it occurs in about 8 percent of males and only about 0.4 percent of females. Isolated communities with a restricted gene pool sometimes produce high proportions of color blindness, including the less usual types. Examples include rural Finland, Hungary, and some of the Scottish islands. In the United States, about 7 percent of the male population – or about 10.5 million men – and 0.4 percent of the female population either cannot distinguish red from green, or see red and green differently (Howard Hughes Medical Institute, 2006). It has been found that more than 95 percent of all variations in human color vision involve the red and green receptors in male eyes. It is very rare for males or females to be "blind" to the blue end of the spectrum.

Some of us see only 25 & spots ... You have the advantage if you get to see 56 also.

Usually if you are color blind, any daughter's male children will possibly be color blind. Daughter will not be color blind. We usually receive color blindness from our mothers who pass it on from their father.

I'm good.

Why isn't this a poll? The ban on polls has been lifted (read my sig). This thread isn't very scientific.

Did they consider color-blindness when they designed traffic lights? It could fatally suck if you confused red and green.

That is why they have a specific order in which they change.

Like this:

i dunno if this is true or not, but i hear each light has a little bit of another color in it that color blind people can distinguish. that way all the lights don't look the same to them. the order thing is true though too.

[Rezinha]

I'm not.
And women perceive more colors than men because we have more cones in the eyes.
That's why I can distinguish dark pink from red, something that my dad can't.

Bite your tongue. Polls are still banned. Some people feel that it is OK for them to ignore the ban. Such ill-placed arrogance has no place here.

"Green" comes in a myriad of shades, as does red. I have always perceived the Green light as that of a very "whitish" color, and yellow is no problem, as I see it as any non-color blind person. Red looks red to me and appears dark. The difference between the red and green in a traffic signal is like night & day to me. Absolutely no similarity or confusion as to which is which. I actually have more difficulty with greens and browns. There are so many different shades of greens and browns that many don't even look related. I would say the one that looks closest to what I see as a traffic light green would be "tea" green in this chart. To me it looks more off-white than green! But I'm probably wrong, lol. All my life people who know I'm color blind say, "what color os this, what color is that?" gets a little boring after a while lol.
