You don't need any equipment for that game.
The players are standing on one side of the playing field, the tagger is standing on the other end. The tagger may should the name of a color, then both groups change their sides. During that, the tagger may tag all players by just touching them. However, all players that wear clothes in the expressed color are immune.
All players tagged stay with the tagger and help him in the next round(s) to tag other players.
