The point of my study today was to darken and lighted a pigment with blacks and whites to change its shading and perhaps generate a three-dimensional effect. In the figure to the left, I made a transition from light blue (blue + white) to very dark blue (blue + black). From the darkest blue, I gradually introduced its complement, orange, gradually adding orange to the black and making the transition to and orange/white combination.  I used the same formula with red pigment on the figure on the right hand side of the paper.

Only when I finished the composition did I realize what a creepy looking mask it was.
