I have often wondered why human colour vision is not evenly distributed across the spectrum of visible light. Daniell Dennett (I think?) had a good explanation of this: Q: Why is the sky blue? A: Because leaves are green and berries are red That is: our colour perception evolved in a particular environment and is optimised towards doing well in that environment by contrasting things that we care about (in that environment).
