These are some photos of good colors for high altitude flying..Transparent Yellow
in particular shows up well when the plane is high overhead. The sun "glows" thru the covering
Where there's structure: leading edge, trailing edge sheeting, the color makes little difference,
so it might as well be black as in (#1).
Black has been found to the be the optimum color for sighting something in the air. You may not
always be able to discern the orientation of the object, but you usually can see where it is.
Colors tend to go to grey at any distance. The more colors there are, the shorter that distance becomes.
The yellow patches in the Parasol Kadet (#6) are effective, but at the distance a Kadet can be flown, not too useful. Likewise the Lifter (#4) will never get to any distance or altitude under normal flight conditions. But it does look good. For long distance flying where the plane isn't high, but far away, a white fuselage is easy to spot when the background is dark. Against a blue sky, or mountains.. but in a cloudy sky it goes away very quickly. Here again black can be the optimum color. As the image when viewed from other than directly below is smaller, black can make the most of the useable viewing area.
