Course work: Painted the red-to-blue row, using cadmium red light and ultramarine blue. These colors are near-opposites on the color wheel: one would expect neutral colors to result from the mixtures, and that is exactly what one obtains: a mid-brown, a near-black, and a blue-grey. (Parenthetically, the closest mixture to black that I have found is burnt umber and pthalocyanine blue.)
Proceeding to Stage Two of the exercise, I did the first part by mixing an orange from approximately equal quantities of cadmium red light and cadmium yellow light. I then painted two columns of squares, one with increasingly darker mixtures made by adding ivory black, the second with increasingly lighter mixtures made by adding titanium white. It appears that the darker column will have to be repainted owing to inhomogeneity of paint application. The darker squares in this column have a slight greenish cast, presumably caused by the slight bluish cast of ivory black.
Reading and theoretical studies:
Michael Wilcox Blue and Yellow Don’t Make Green
North Light Books Cincinnati, Ohio, USA 1994
Pp. 48-94
Sketchbook work: A second set of color experiments, using Prismacolor pencils in ultramarine blue and those selected as the closest matches to cadmium red and cadmium yellow. As expected, results quite similar to earlier color tests were obtained, indicating that my color selections were reasonably correct.
Time today: 1 hour 26 minutes
