This must be true could so many say the same thing here, but the glider looks almost black to me when it is so high, and since it is the underside that we look at, I have always thought a say, light yellow would be the pick?
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
