Colors are insignias worn by members of a club to indicate their membership or participation in that organization. Colors are usually patches that are sewn onto leather vests, leather jackets, levi vests or overlays or uniform shirts. Colors usually come in two sizes, large patches for full members and small patches for associate members.
Clubs will present their colors, usually on a banner or in a frame, to other clubs to symbolize their friendship and social relationships .. both sexual and platonic.
