I used yellow-orange and blue violet...which photographed pretty accurately. The muted colors are, however, not as they look in person. Most everything should have a more green cast, and should appear more grayed down, especially the blues. The collage with the light dots running vertically looks very much green in reality, not blue, although the intensity of that one is the most accurate. Go figure! Had a good time doing these despite my troubles with taking the pics.
