Isaac,
It works very well for me and is very high contrast under all conditions. The bottom is simply the outer 30cm of the wingtips in red. Gives the illusion that the plane changes wingspan during rolls and spins.

This top scheme is not mine, it was originally used by Ivan Kristensen in the '80s. I add the bottom scheme on my planes during the '90s.
With amber sunglasses, the contrast is stunning.

Thanks,

John
