Hello everyone!

I am about to start covering a trainer (PT-40) for my little brother and am utterly confused as to how the color arrangement on the wing should be. The first trainer that I built was covered completely with solid color monokote. I later found that I needed to add a couple of stripes on the bottom of the wings for better visibility. I want to avoid such visibility problems this time and am trying to make a good color scheme. I am using white and blue monokote. Is the bottom of the wings supposed to be dark or light? I am gonna attempt to replicate the covering scheme that is on the factory PT-40 but I noticed that white is used for the bottom. Any suggestions are appreciated.

Thanks in advance!
