RE: SPEED DELTA PILOTS-OLD MAN NEEDS HELP WITH COLOR SCHEME
All basic black with white and yellow stripes only on top, [on the outboard wing panels where you want to detect the slightest movement].. Least amount of confusion if you can tell at a glance which end is up. Stay away from white, gray and light blue as the main colors.
Red is another good main color, with white highlight striping on top side only....leaving the bottom a plain single color.
