adj. -- Ordered (as a set of items) in the color sequence of the spectrum or rainbow.

Word origin: derived from "alphabetical" order.
Little Suzie was instructed to color a rainbow in her kindergarten class, but she ended up putting the yellow stripe of color next to the blue one, instead of green. Her teacher looked over her shoulder and said, "That's not in rainbow-betic order, now IS IT, Suzie?"

From that day forward, Little Suzie was so traumatized that she became frightened of the rainbow colors in order. She never took an art class in school in which she had to make a color wheel, and she started rejecting her two gay dads for the sole fact that each of them had a rainbow flag bumper sticker on their cars.
