Recently a very talented pastelist suggested trying color block studies. So choosing to do two color variation studies using the same reference , I started with two quick color blockings on half sheets of white colorfix . I used a red - orange warm and blue cool under painting . I blocked in using a Nupastel and then used alcohol to fix the color. Though these are not finished I am having to much fun playing with color , try it , I feel I have learned a lot.
