A character has two hair colors that are split vertically at the top of the head, then fall like the colors are cut in distinct halves. The colors might not be a 50/50 split (post #566775), and the colors might be mixed together (post #4898598), but the colors should be distinctive enough to tell them apart. Different hues of the same color are acceptable, so long as they are easy to distinguish (post #1323509).
