In my opinion, a blind person can surely distinguished two colors " Black and a white"..:-) and may be later through the help of a family members or friends and some expertise a blind person may or will have a perspectives about others colors. Anyways, we human came from nothing but born for something. Isn't? Hence then all things can be learned or practice.

I think his question is not about Color blindness. It's about how do blind people perceive color at all.

Most blind people are not totally colour-blind and easily distinguish between certain colours or variations between two colours. For example, if a person is a blue-green colour-blind individual, it means that he or she has trouble distinguishing between the colours blue, violet, pink and grey. A lot of individuals who are colour-blind, in fact, can still see shades of colour. It is popularly believed the individuals who are colour-blind can only see the two basic colours, namely black and white, but that is an incorrect statement.

For instance, it is not clear whether a colour-blind person cannot see a rainbow or not. A person who is blind (even though the phrase visually challenged in a more politically correct term) cannot see a rainbow. On the other hand, a colour-blind person is a person who is unable to distinguish certain colours, such as red and green. Red and green appear to be the same colour to an individual who in colour-blind.
