It seems that I can recall attending a Laserium concert in which several colors of laser light were superimposed on the same spot without mixing; in other words, that all the several colors were simultaneously and distinctly perceived. When I mentioned this phenomenon to a friend, I was informed that a similar effect is witnessed (if I recall the comment correctly) as a result of certain diffraction patterns, though I don't recall any 1st person example of such.
