Dear Justin, The key word of your question is "appear". You are probably aware that this makes it more of a psychological than a physical question. The whole business of color involves those two fields. I don't think your question can be decided one way or the other. It is my guess that it depends more on the way the two colored areas are separated from each other, on the size of the patches, and on their hue, whether one appears to be on top. In a landscape painting, parts that should appear far away are painted in blueish, unsaturated hues, with fuzzy borders, whereas closeup objects are rendered in more saturated tones. I think painters like Rothko (in some of his abstract works) went to great length to avoid the impression of a 3-D space, and to keep the appearance 2- dimensional. Best Regards Werner Sieber
