This was such a nice, splashy rainbow that I decided to pay tribute by arranging them in actual Roy G. Biv order, although of course Mr. Biv isn’t as welcoming of gray areas — literally, and also in terms of other hues that don’t fit his acronym — so it’s really more of Roy G. Biv PBG, which sounds like some kind of advanced official position. PROFESSOR of BIG GRADIENTS. Or PANTONE BREADTH GUARDIAN.
