The most important thing to learn about colours is contrast.

Yellow has a different perception when its with blue than when its with red.

One interesting story about colours I read recently is that in Quebec, Canada - Unilever doesn't sell as much of margarine as they do in other parts of the world. And the reason for that is the Quebec courts have passed a law: making margarine yellow instead of its natural white is illegal. Everywhere else, additives are added to margarine to make it yellow - so that it looks more like butter.

And when it looks more like butter, it automatically tastes more like butter too.
