Many people think anyone labeled as "colorblind" only sees black and white -- like watching a black and white movie or television. This is a big misconception and not true. It is extremely rare to be totally color blind (monochromasy - complete absence of any color sensation). There are many different types and degrees of colorblindness - more correctly called color deficiencies.
People with normal cones and light sensitive pigment (trichromasy) are able to see all the different colors and subtle mixtures of them by using cones sensitive to one of three wavelength of light - red, green, and blue. A mild color deficiency is present when one or more of the three cones light sensitive pigments are not quite right and their peak sensitivity is shifted (anomalous trichromasy - includes protanomaly and deuteranomaly).
There are several different kinds and degrees of color vision deficiencies. Protanomalous or deuteranomalous individuals can usually pass as a normal observer in everyday activities. They may make occasional errors in color names, or may encounter difficulties in discriminating small differences in colors, but usually they do not perform very differently from the normal except on color vision tests.
The protanope and deuteranope, on the other hand, can be severely color deficient. The real problem, as a protanope or deuteranope may see it, is there are far too many hue names (color names) used by most people without any obvious basis for using one instead of another. Why call something "orange" when it doesn't look different in any way from something else called green, tan, beige, or any of several other color names?

There are different types of color blind. I am red-green which means I have a hard time telling the difference between a Teal and a Purple depending on the shades. We do not see in black and white or shades of gray, I see the full spectrum of color, it's just certain colors get a little hard to distinguish. The colorblind tests (the ones with the multi-colored circles and the number in the middle) are designed to distinguish which type of color blind you are. When I found out that I was color blind when I went into the Army I thought WooHoo! But then the let down, the Army sees color blind as an asset, you get used as a spotter or sniper (during Viet Nam) because you can not distinguish the greens and enemy camouflage becomes useless. It did not matter, the army sent to Alaska where everything was white, lol.

They see all colors just not the same way we do. It would be hard to tell since they really can't explain it themselves as they have "seen" the same way all their lives so they don't know the way a normal person sees.
They see some colors fine and others look muted or the same. The most common is Green and red. My Dad had a freind that if you threw a basket ball on a green lawn he couldn't see it! I had a freind when I was in drivers ed that the teacher found out was color blind. We had a chalk board in the front of the room that was a light greyish-green and one on the sid that was a rust color. To him they both looked the same. He said they were both kind-of brown.
My Teacher also told us a story of a traffic light they used to have in the next town over. They put one on top of a pole but used the same type that usually hangs from a cross-bar so the power comes in from the top (above the red) since the power had to go through the top and they were attaching it to a pole they placed it upside down on the pole because the power came up through the pole from the ground. It took several accidents before they figured the color-blind people were just watching for the top and bottom lights because they looked the same color to them!

Well... none of those are right. What happens is that colors are perceived as a different color. Blue/Green for example makes people unable to distinguish certain shades of blue and green from one another and from what I have been lead to believe they either see them both as green or both as blue. There are many different kinds of color blindness. It does not mean that the person is incapable of perceiving all colors, it just means they cannot see certain shades of colors or distinguish between them.

Depends on what type of colorblindness you have. Some people can only see shades of gray while others can see everything except for red and green.

It depends on what shades of color they are colorblind in and the persons personal interpretation. Some just can't tell the difference between colors like red and orange whereas others can't see any color at all. It depends on the severity of their color blindness.

Oh stop that folks. Color Blind people see colors, they just can't distinguish between some of them. The most common problem is red/green, which is why traffic lights use some blue in that green light. There are other pairs that are a problem though.

depends which color blind you mean , full color blind people only see black and white (various tones of it of course) , and some are red and green color blind where they can only see red and green (i think thats how it is) and then theres a purple and yellow color blindness too which they can only see in those 2 colors.
there are also different kinds where they are similar as to what is said above , they see colors but have problems differentiating between the colors mentioned in the previous statement.

you may on no account circulate incorrect with a khaki/tan colour pants or shorts with any colour shirt quite. Khaki is going with maximum each and every thing. Yeah blue and black do not look that warm together. Why not attempt black and pink or black and gray? in case you like to placed on army blue do it with the two an rather diminished or gentle denim backside or tan bottoms. do not placed a depressing top with a depressing backside. and don't use 2 completely distinctive fantastic colors together. attempt to make advantageous your shoe colour and shirt colors journey or the two your shoes and belt journey. desire this facilitates!!!
