I go with names from the Ancient World.

My Normal is Bacchus after the Roman god of wine and festivals.

My Pastel is named Osiris after the Egyptian god of the underworld (GF named that one).

My Mojave is named Cupid after the Roman god of love. Picked him up on Valentine's Day, so that one was a natural.

My Cinammon is named Mars after the Roman god of war.
