Rainbowetically

When something is arranged by color, following the order of the rainbow.

Sometimes a result of Obsessive Compulsive Disorder.

David felt compelled to arrange his collection of rubber ducks rainbowetically; starting with red, and ending with violet.

Rainbowically

To colorize items, in the colors of the rainbow.

My grocery list has been colorized rainbowically.
