"Monochrome in Ochre, Crimson, and Ultramarine"

In this painting I attempted to create a monochrome image using only the primary colors, red, blue, and yellow. There is no black or gray in the painting. Only the three primary colors plus white were used. This was done as an exercise in value and color control.

As you can see, the painting came out rather blue. But that is OK because I like blue, and it is still monochrome even if it looks blue.
