Choose a home base. One player is "It". The other players are the Rainbow.
They each think of a color to be - without saying their color out lo
ud.

The person who is "It" calls out a color. When a player's color is called, they run for the base, and "It" tries to catch them.
If they reach the base without getting tagged, they choose another color and rejoin
the rainbow.
If they are caught, then they are out.
