What do colors look like to color blind people?

If somebody is color blind are all colors "distorted" or just a few? Are there different degrees of color blindness? I've heard of people that only see shades of grey, no bright colors. But I've heard of others that seem to only have problems with only specific colors. Anybody know about this?

1. its diff for everyone
2. just a few colors are distorted I think, I had a teacher who was color blind and he would see color just not the right colors
3. i had a color blind teacher and he thought that my green jacket was red.
4. black and white
5. i think how you explained it is true,. but i think that they can see red...
6. There are several levels or degrees of color blindness. Some just can't distinguish variations or shades of a particular color/colors and some see everything in shades of grey.
7. I don't know that your question can be answered. Unless someone was not color blind and then became so, there would be no frame of reference for describing it. I would guess that the colors would be represented in grey scale such as you see in a black and white photograph.
8. there are a bunch of different ways people see when colorblind check out the link below and you can see how they see . there are a few different types
9. Red, Green , or Gray
10. That's a question with many answers. When i attended drivers ed cladd a student next to me was color blind and i asked how, and he said that at a traffic light red lights are purple to him. Or another kid at my school has peripheral vision in which he can only see blue out the corner of his eye. Color blindness is different on everyone, some have it mild while others have it so bad to where colors are floating everywhere.
11. I am red-green color blind and I see color vividly but I cant always differentiate b/t colors that are close. i.e red/green blue/purple orange and red. Interestingly I can't see hunters orange in the forest. Its worse in artificial light
12. Colors to me look like for example.... a traffic light green looks like a bright white yellow looks yellow red looks orange I know the position of the lights also... no problem
13. For me, hunter green, navy blue and burgundy cars look alike in artificial light. When they are in the sun I can tell the difference. (Most of the time.) But in artificial light, black, blue and green look the same. I don't know if I would call it grey, but they all look "off black". The color also does not look the same. It changes every time I look at the object. Sometime I think it's green, black, or navy. I had a job as a service advisor in the past. I had a hard time telling the colors of cars. I would ask my fellow employees, but sometimes they would mess with me. That's not cool.
14. It all depends on the type of color blindness that person has. Some people can only see in black, white and greys, while other people only have problems with a specific color or colors. There are cones in your eyes for red, blue, and green, which are sensitive to those colors and combinations of them.If one doesn't work right, your brain gets the wrong message about exactly what colors you are seeing. This is why something green can look brown or gray to someone that is color blind. It really just depends on that specific person. There are many different ways to be color blinded.
15. It is different for every person. Depends on the kind of condition. Some people oare blind to certain colors, others exchange the colrs that they see adn stuff like that.
16. My color blind friend just got them mixed up. He often saw purple as blue, etc
17. I'm color blind... and yes there are different degrees or levels... Normally a color blind person is unable to see a certain basic color (normally red or green), at least in a normal way. There are a few cases of people who can not see colors at all... but this is pretty rare. I have a green mild deficiency... I can only see certain green tones, but other tones look either gray... or yellow... or red... or white... depending on the tone of green. To me a stoplight is red and white... not red and green... Other people have trouble with red, and another few have trouble with blue.
