Question

Fran, via SMS asked:

Were taught that the grass is green and the sky is blue but do all of us see these colours as the same?

Answer

Ben - I think its partly cultural but ultimately, the actual frequency of light that our eyes are picking up is going to be same for green as it is for everybody else.  But then if were brought up being told that green is in fact blue then, well always going to think that green is blue.  Kat, what do you think?

Kat -   Yeah.  I think we had someone on a while ago who was talking about the science of vision and basically the red I see is not the same as the red you see.  Its because the frequency maybe the same but it really depends how the brain interprets it.
