yellow, Actually disregard my comment on light to dark to hide size. It only works if the background meaning time of day is that color hence if it is night time. And the front of a car was white that faded to a black wing the wing even if large would look small. But on a bright sunny day the black wing would stand out and look stupid. Same goes for opposite if front was black and wing was white. At night the wing would stand out and probably look stupid, but during the day the wing would look smaller in light.
