There once was a proposed TV show called “Sky Rat” about a rat with amnesia that learns to fly from a group of pigeons.
The show never saw the light of day but, Skyrat the paint did. Its dark purple, magenta, and blue colors reflect that of your garden variety pigeon. Beware this may fly off the shelves.
Note: Skyrat must be used over a black basecoat to see the shift effect. If used over white, it appears grey.
