This post is especially for my friend Kay who is falling in love with oil. Six years ago I purchased Richard Schmid's book, Alla Prima. Pages 132 and 133 show color charts. He describes making the charts as 'an astonishing experience' and I agree. I loved making them and am glad I found them again recently during my big studio cleanup. Now will be a good time to reread the book and put what I learned then into practice on this summer's little oil color studies.
