Ooh, red white and blue, and ... army green?
Mixing colors gets interesting too, just for fun. Certain combinations don't bind to each other as well so the coating can be weak, but if they're all the same brand it can have some neat results.
The most unexpected result I got was from mixing some bright red (like yours) with some bright green, kind of a Kawasaki green or zombie green - it made a mottled olive drab, but looking real close you could still see the separate green and red.
