Colour blindness is not a disease. It is a condition arising from a lack of sensitivity in the retina to various colours so that a person cannot distinguish between certain colours (typically red and green or blue and green) of the same intensity. There are several different types, the most common being red-green and blue-green in which, respectively, red and green or blue and green are seen as shades of the same colour and a person will not be able to positively identify one from the other. Most of the questions you ask above are answered here: http://www.colorvisiontesting.com/ This article has pictures of how people with different forms of colour blindness see the spectrum colours: http://en.wikipedia.org/wiki/Color_blindness This article (and site) may be useful to you as a graphic designer: http://webaim.org/articles/visual/colorblind/

I find that the first link I gave you: http://www.colorvisiontesting.com/ seems to have many broken links. In particular, I cannot get the "Frequently Asked Questions" page to load! The answer to whether colour blindness can be cured is, generally, no, if it is a congentital condition. If, however, colour blindness occurs later in life (through nerve damage or because of a cataract), it can, potentially, be corrected. In the case of a cataract interfering with colour vision, removal of the cataract should correct it; nerve damage would, of course, be much harder to correct.

Thanks a lot for your feedback. Now I would like to ask doctor about colorblindness.

In a nutshell, color blindness comes in many forms I think. There are two distinct forms. There are some people who get it to a small extent, where similar looking colors are hard to distinguish but it is still obvious that they are colors. Then there are others who really get it so bad that they can only really see in black and white. While this is not rare, this is much rarer the first area of being color blind that I talked about. You're more likely to get this as you are older. I think that a little over half of all people into the senior age might get this to some extent, but their vision fails in other ways anyway. However, it is really not all that uncommon for a younger person to become color blind or even in some extreme circumstances, be born that way. It is not something that is particularly pinned down to one degree. Its not either you are or you are not, but its all over the board.
