Moonspear keep on twiddlin' them thumbs

Alaric arrived with berries in tow and added them to the nearby cache. He smashed them so they made blue, red and purple colors. The blue and the red were similar, but if looked in the sun. It was clear they were different. Following that he spoke. 

Watch you can make different colors with each other.

He took some of the bluish berries and mixed it with a dab of the yellow and it turned green like trees and grass. 

But you don't want to mix them all together or it will turn brown. Unless you want brown like tree bark and dirt.
