The runner up for the title was ROY G. BIV (well, it makes sense if you took physics along the way - that's Red Orange Yellow Green Blue Indigo Violet for the liberal arts majors, otherwise known as the the colors of the spectrum). The morning sunlight streaming through the thick tempered glass of our shower stall makes little rainbows on the floors & walls of our bathroom. Decided to see what the D300 and a wide angle lens would make of it. Now I know. Next I'll try it with my IR converted camera. Any guesses on how the IR will look?
