This is a painting I did in 1986 in honor of the style of my Portland State University Professor Frederich Heidel. When I was a student I made a proposal for a mossaic in the Portland State cafeteria. I did not get the commission. But I did write a paper about a color theory of using tinted grout in back of broken glass and ceramics. In addition to setting limitations on color, I addressed the different kind of shapes off the more brightly hued chards. This theory is adapted to paint.
