Black and Red

Detail

For the black I used ultramarine blue and burnt umber. Adding the "black" is really giving the piece the punch I wanted.

After finishing the black, I painted the red. You'll notice that the "red" is a different color middle-top than at the sides and bottom. The upper middle red is cadmium red and cadmium orange. For the darker red I substituted burnt sienna for the cadmium orange.
