Here's mine - I try to dance with a guy wearing every color of the rainbow - that adds up to nine when I throw in black and white.  If a guy asks me to dance I note his color and then subtract that color from the list.   Of course I try to give colors to my favorites but I truly love the randomness of this technique.   It makes for joyful and surprising dances.   I love variety - also  keeps me from be snobby or being snubbed.   I leave the dance when I'm done with my spectrum.  Sometimes I'll wait hours for cyan to arrive.
