Then, I made a print of the black and white painting and used colored pencils to color it to see what colors I liked. There were lots of ways I could have colored it like with a blue water background. I settled on this one.
Working slowly with multiple layers gives more luminosity to the image. Then I make a three color palette with matte white mixed with yellow, pure white, Unbleached titanium white and also a mixture of white gesso and cadmium yellow to paint the background. This painting is 20×20″
