What Colors Do Blind People See? How Do They Know What Color It Is That They Are Seeing?

Answer Question

1 Answer - Sort by: Date | Rating

    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.
