It's strange, though, that it hasn't gotten a politically correct acronym yet... Like CVD for color vision deficiency.
I have trouble with red+green, but actually it's only the red color component that is the problem. I perceive red color less vividly than other colors, so I for example have trouble viewing red text on a black background, while I clearly see green text on a black background.
So, if you feel that more computer geeks are more color blind than average, vote "blind".
No, that is not correct. The question was if you were color blind, not if you think that others are color blind... Freely interpreting the question as what you think that it should be really would skew the statistics...
Despite everything, the person most likely to be fooling you next is yourself.
Where I grew up there was a clear distinction between a deficiency and total blindness, this is also distinguished by the standard tests. (And definitely not for political correctness - that had a completely different meaning )
No, that is not correct.
I was more expressing how I value such a black&white question.
I am quite color-blind, about as bad as you can be without seeing just pure black and white. Without contextual clues (like the order of the stoplight, jeans are usually blue, etc.) I have a really hard time distinguishing these color combination:
Red-green (really common in men)
Yellow-green (a real problem with LEDs in electronics that I work on)
And any kind if "subtle" (mauve, salmon, taupe, etc.) or non-primary color is kind of lost to me.
This is caused by missing "cones" in my eyes, an inherited condition.
"Color blindness (color vision deficiency) is a condition in which certain colors cannot be distinguished, and is most commonly due to an inherited condition. Red/Green color blindness is by far the most common form, about 99%, and causes problems in distinguishing reds and greens."
But, my point is, as software engineers, it's really important NOT to put such a huge percent of users needlessly in a difficult position. For example, never use color as the primary indicator of state; combine color with an icon or text. Use "color blind safe" pallets. There are examples of these on the Internet. If you go out of your way to have a color-blind-friendly product, chances are it will also be better for normal users.
PS. I've never had a problem seeing a traffic light, although I did once try on a pair of purple jeans in a store!
