Years ago, I covered a plane in multiple colors so that I would be sure to know the orientation when I looked at it. I don't remember the exact colors, but it was something like right 1/2 of wing orange and left 1/2 of wing light blue. I then made the tail yellow (or something). I made the bottom different colors too! So basically, every major area was a different color. This was supposed to help me determine the orientation of the plane at a glance.

2 problems:

1. There were so many colors, I could never remember which one was where. Is green bottom right?? hmmm.

2. It was the ugliest damn plane you ever seen. It looked horrible. People commented: "damn! that's ugly!" 8-)

Needless to say, after a couple of flights I recovered the whole thing with a design that looked similar to the box cover. Much better!
