I've got a marble(?) female who likes to be white, red, blue, purple, black, and green. And those are only the colors that I can see when she stops moving, which isn't for very long.
And I have a green, blue, white, and red crowntail.
Not sure if Starscream counts since his body (minus the iridescence) is a solid color and his fins are a different color, but here he is.
