It depends on how color blind they are. Blue-green colorblindness is most common, particularly in men, which means they can see every other color just fine, but when they encounter something blue or green, it's grey. Complete colorblindness is like watching everything through a black & white tv

My uncle is colorblind, but I don't think it's severe... he can't really tell the difference between dark colors, like black, navy blues and dark greens. And he has trouble with warm colors too, he'll see yellow as a light orange color or pink. The best way to get info on this is to just search yahoo for "color blindness"..

go to this web site for simulations:
http://www.vischeck.com/examples/
If you go to vischeck: http://www.vischeck.com/vischeck/
they let you use their simulation program on either your own image files or on your (or anybodies) website. So play around with it and explore.
Given that there are a significant percentage of colorblind people (some claim that it is as high a 8% of males, that for red green blind or which is also called deuteranope) if you have a busy website it is polite to make sure you don't use color schemes color blind people find hard to detect (e.g. use magenta instead of read to draw attention to an item). So this tool lets you design color-blind friendly websites!

to function to the above: actual black and white shade blindness is rather uncommon and oftentimes, yet no longer continually, linked with undesirable commonplace imaginative and prescient. the vast majority of human beings with shade imaginative and prescient defects have the milder variations, and purely have concern with a limited variety of colorings, particulalarly whilst they are de-saturated (pastel , or close to-white) tones. approximately one guy in fifty is judging site visitors lights fixtures via their place on the pole, no longer via their shade (an occasion of double-coding: the lights fixtures are giving advice 2 distinctive techniques: *pink* lit potential end, yet so does *actual* lit.) some colorings, somewhat blue and yellow, are very virtually continually secure and easily discriminated whether others are possibly to be perplexed. there is not any treatment yet there are tricks and synthetic gadgets which improve the skill to discriminate shade specifically circumstances for some human beings. The temporary (yet no longer everlasting) use of a colored filter out, case in point, will enable discrimination between a pink and eco-friendly merchandise. using the X-chrom touch lens and suitable gadgets additionally will improve discrimination in some persons, yet does not create "widespread shade imaginative and prescient." I would desire to declare that i'm somewhat worried approximately your novel, provided that your question is composed of a minimum of 8 infelicities or errors of English. i'm reluctant to declare this, yet somebody has to, like informing your ultimate pal approximately her breath. you won't get thanked, besides the indisputable fact that it is the ultimate suited difficulty to do.

In nearly all forms of colour vision defect, blue and yellow are "safe" colours, identified as well as anyone else. There are very rare individuals who do see in black and white, but they usually see only poorly.
The two most common types of defect share confusion over red/green, but differ as to which other specific pairs of colours might get confused. (One sees red as a very dark colour, and tends to confuse grey and pink, the other does not.)
The degree of problem varies markedly, and is much more common in males. Many people only have mild difficulties and will not have any problem with "Traffic light" red and green, but still have difficuties when faced with very pale, pastel, reds and greens.
A colour vision defect is not normally a bar to an ordinary driving licence, but it can restrict many choices of career including heavy goods vehicle driving.
It is possible to temporarily simulate a colour vision defect in a normal eye by exposing it to red light at a bright but safe intensity. This "tires" the red cones, and on looking at a colour vision test plate for the next few minutes red and green dots will be difficult to separate.
