Tell you what does work well on built up wings is an almost transparent white covering. This allows the sunlight from the top side of the wing to pass through to the underside. It looks bright & white
Even though they are almost on opposite sides of a color wheel, and you might think they would contrast well, light yellow against light blue would be very difficult to see at a distance. Remember, we're talking about being up very high, nearly specke'd out. A dark underside will allow you to keep it in sight higher than you would be able with a light underside.
