parti-colored (adj.)

1530s, party-colored, "colored differently in different parts," from party "divided," from Middle English partie "of different colors; different" (late 14c.), from French parti, past participle of partir "to divide," from Latin partiri "to share, part, distribute, divide," from pars "a part, piece, a share" (from PIE root *pere- (2) "to grant, allot"). The noun parti itself occurs in the sense "parti-colored" from late 14c. Also parti-coloured.
