The BBC program Horizon produced a great documentary on the perception of colour. It covers a lot of great ideas around colour from a science-based perspective as well as how different cultures understand and communicate ideas of colours.
It is amazing how much colour can literally change our mind on things.

Edit: colour and color are the same thing just different spelling, fools.
