A study was done in england to find the best color/pattern for
increasing glider visibility. They found out that solid black was
best (unfortunetly grp aircraft have to be mostly white, heat issues)
and that bright stripes on a white aircraft broke up the silhouette
and did'nt improve visiblility. I heard the same argument regarding
military use of parachutes, they are grey because all black creates a
definitive outline even at night.
