Are you colorblind, how many on Yahoo Answers are?

Question

It still amazes me that people can be colorblind. I had a chem professor who told the class he was colorblind and I wondered what did he see, what were his experiences? Did he see life in grey colors, limited colors?

Are you colorblind? If so what are ur experiences? What do you see?

Answer 1

For most people, and it's common, it just means they have a few fewer colours on their palette that they will use to name what they see.
About one man in ten has a detectable but minor defect, about one in fifty are judging traffic lights by their position on the pole. (An example of double-coding: top AND red means "Stop")
The condition is much less common in females: about one in six hundred. (They should always be allowed to pick the curtains.)
For people with the milder forms of the condition, it principally affects pale colours, pastels. Strong reds and greens, such as traffic lights wil not be confused.
Some colours are not really affected. Blue and yellow are (almost) never confused,

I've had to think how to explain the experience to people who enquire, and I've even made people colour blind for a few minutes, enough so they fail an Ishihara colour vision test, using a red light.(don't do this at home).

How about this?
If you were a bit taste-blind, you might recognise the taste of "apple." But you would be rather perplexed when other people insisted there were DIFFERENT tastes of apple...
(A Russet is not a Coxs' Orange Pippin, is not a Fuji is not a Golden Delicious)
And they would be perplexed when you insisted that they all tasted of "apple"
They then ask: "But what exactly does that taste like? like the Russet, or the Fiji?"
Which to you is like them asking:
"But what exactly does that taste like? Like the apple, or the apple?"
