Interesting piece from New Scientist about another possible origin of colour vision in primates.

The existing theory reckons that it developed to enable us to detect ripe fruit more efficiently, but this new theory measures the almost exact match between the human eye's sensitivity to colour and the range of colours that facial skin goes through when blushing.

In short, colour vision may have developed as a way to tell what someone else is thinking, and whether they might be hiding something.
