Overlap

From BoardGameGeek:

Deal every player seven cards, each of which is segmented into 9 sectors. Each sector is white, red, blue, green or gray. Seed a discard pile and then take turns playing cards onto the pile. Draw cards equal to the number of sectors on the played card whose colors overlap with the colors of the sectors on the top card of the discard pile. Ideally that number is zero. The first player to shed his deck wins.
