Flying Zee,

Major Tom is right! Also, if the majority of the plane is already white, try covering all of the tail surfaces with a dark, contrasting color (black, red, etc). When the plane is at a distance, this helps tell one end from the other, as well as pitch attitude. Navy trainer schemes often are examples of this type of scheme. Orange dayglow actually shows up well.
Each of us have a certain color combination that shows up better. Mine seems to be red, white and black. As your experience grows, your effective combination will become evident.

Good luck and happy flying with your new plane.
