These paints stirred together give some kind of brown.

But that was not the point.

You wrote, that it takes yellow and blue paint, to create green.

But there are substance, that have a green colour, but neither blue or 
yellow in it.

Your error is, that you use features of the human eyes (three types of 
colour-receptors) and ascribe them to the objects seen.

This is wrong, since seeing and objects seen are different things.

So: colour is an impression of the human brain about the objects.

And mixing blue particles with with yellow ones can look similar to 
green particles. But looking similar does not say, they are similar.
