When a third is added to the mixture of two you have two mixtures mixing at the same time. It is an impossible equation. In practice, nevertheless, it is done all the time.

Where three primary oil paint colors overlap the result is literally gray, in the sense of neutral. The maximum strength of each paint hue neutralizes that of the other. Because two of the three primary colors (of paint)...
