what colour can a person suffering from colourblindness see?

Question

If a person suffurs from colour blindness and may not be able to see certain colours like red and green, then what can they see in place of that? black, grey, white....?

well I know that people suffering from colour blindness can't see different colours, but no matter what the colour is (that they can't see) I wanna know what they see in place of that colour.

Answer 1

Here is an excerpt from wikipedia, hope it is useful for you:

Color blindness is not the swapping of colors in the observer's eyes. Grass is never red, and stop signs are never green. The color impaired do not learn to call red "green" and vice versa. However, dichromats often confuse red and green items. For example, they find it difficult to distinguish a Braeburn from a Granny Smith or the red and green of a traffic light without other clues (for example, shape or location). This is demonstrated nicely in this simulation of the two types of apple as viewed by a trichromat or by a dichromat.

Color blindness almost never means complete monochromatism. In almost all cases, color blind people retain blue-yellow discrimination, and most color blind individuals are anomalous trichromats rather than complete dichromats. In practice this means that they often retain a limited discrimination along the red-green axis of color space although their ability to separate colors in this dimension is severely reduced.

Answer 2

A (normal) person sees all the colors using three different types of color-sensitive cones on their retinas and sees black and white (especially at night) using rods. Color blindness varies depending on whether one, two or all three cones fail to function properly. Color blindness tests can include a circle filled with colored dots where some of the dots form numbers that can be seen only by certain cones or mixtures of cones. If all the cones fail to function the person sees black and white (like old TV sets).

Answer 3

There are varying degrees of color-blindness, from partial to complete, where a person can only see in black and white.
I have a friend who is color-blind, and he says he can see only shades of brown and red. He can't see any color having any shade of blue in it, this, from what he says is the most common form of color-blindness.
