Are You Color Blind?

Last week's Tone Deafness Test was popular, so this week let's talk Color Blindness. I am "Color Blind," though I prefer to say I'm "Color Confused," as I do see colors -- just not, uh, the right ones. I have a condition called Deuteranomaly. Here's an explanation of the condition from colorvisiontesting.com (warning: some "misused" quotation marks are retained):

Deuteranomaly (five out of 100 males): The deuteranomalous person is considered "green weak". Similar to the protanomalous person, he is poor at discriminating small differences in hues in the red, orange, yellow, green region of the spectrum. He makes errors in the naming of hues in this region because they appear somewhat shifted towards red for him. One very important difference between deuteranomalous individuals and protanomalous individuals is deuteranomalous individuals do "not" have the loss of "brightness" problem. From a practical stand point though, many protanomalous and deuteranomalous people breeze through life with very little difficulty doing tasks that require normal color vision. Some may not even be aware that their color perception is in any way different from normal. The only problem they have is passing that "Blank Blank" color vision test.

The description above sounds about right to me, though I have more problems with green than the other colors. I have owned a lot of green clothes that I thought were black or gray until a helpful friend pointed out my fashion faux pas. As a result, I now own a lot of gray (verifiably gray) clothes. I also have a hard time perceiving the color pink -- it usually looks like a light gray; this has contributed to several comical laundry situations over the years! Note: the image at the top of this article supposedly shows the number 49, but I don't see it at all -- I just see a neutral field that looks like marble. (See more images like this at Wikipedia.)

Although computer monitors are often not properly adjusted to show "true" color, you can take an online color vision screening. If that turns up problems, you can take a real color vision test from print sources to identify what's going on. Another online test shows a variety of sample color plates which might help fine-tune your self-diagnosis. Finally, Wikipedia has an excellent Color Blindness page with many links to additional resources.

So let's have it, readers: are you Color Blind like me? If so, what flavor of the condition do you have?
