Each colour in its pure form was put on the paper starting with the yellow, then the red and finally the blue. The painting was set aside and allowed to dry.
I used burnt sienna as an accent colour to paint in a few lines in order to create a little more movement in the painting. I am pleased with the results and may try this again as a larger painting.
