Howdy,

I've been looking all over, and I can't seem to find any discussions on the
relative visibility of various colors for aircraft. I would guess that the
best color might be different when viewed against the sky or the ground.

From flying RC models, I have find that yellow stands out the best. Even in
twilight I can track a plane from the open sky to below the tree line.
