Logical Color

AskPhilosophers tackles a question that's been burning a hole in my retinal geniculate receptive antagonistic sub-field.
Are there logical relations between colors? For instance, is it logically true that red and blue make purple?
See the answer here. Unfortunately, it's not nearly as exciting as the question. Some questions are better left unanswered. Some questions simply don't have black or white answers.

Scientific American recently published an article about "impossible" colors. When I did the experiments, I didn't see anything but splotchy combinations or overlays of our usual colors.

Perhaps I have developed too logical a relationship among the colors in my mind.

Not black or white, but not so gray either, in the light of day.

Color relations aren't any less absolute than relations of left and right to dance the rhumba or between disease and dosage. These are just idealized anthropocentric rules of thumb, not to mention political decisions affected by who we're considering a person.
