[MD] Helpcolour recognition

[David M]

Hi folks

Can anyone help?

Now I understand that colour recogntion ability is
hard wired into the eyes and brain. Yet naming colours is
a cultural phenomenon/SQ.

For example, I heard about a tribe that had no distinction
between black and blue and that when the anthropolgists
showed them the line on a card between a black and
a blue half the tribe folks could not see a thing and said
it is all the same colour.

Anyone know of any work done on the brains reactions
to colour, neurons firing when colours change, to show if
there is a link between culture and the brain's ability to
differentiate between colours.
