Color theory makes my head hurt. Having said that, I used a limited pallet for this painting, using only cadmium orange and ultramarine blue, black and white and small touches or viridian and cadmium yellow. The canvas was under-painted in a light lavender. As I continue to work in casein, I’m using two complimentary colors as found on color wheel, and mix all other hues in between with the complimentary colors selected. I’m relying on the wheel until its principles become like second nature to me when I paint. It’s tedious but I like the result of more harmonious paintings.
