39	Better docs for mixColors	Ben Lippmeier		"
From the list:

The named tertiary Colors are defined using addColors. For example, orange = addColors yellow red. That gives unexpected results. For example, orange == yellow is True.
 
A more expected result would be if the Colors were mixed in equal ratios. For example: orange = mixColors 0.5 0.5 yellow red

> Yeah, it's saturating addition, which is still associative and commutative. I think this is a legitimate operation with respect to physical displays, though perhaps it needs a different name. 

> The way I think about ""addColors yellow red"" is ""turn on all the lights to make yellow, and all the lights to make red"" .. which still gives you yellow.
