Dang, that's a great question. I can't offer any suggestions about which scheme to use, but during my plane search, use of Imron paint seems to be a selling point because of durability, might be something to consider, whichever way you decide.
Finally, have you done the math to decide how much paint affects the selling price? It's possible that it doesn't really matter one way or the other, in which case it's up to what you personally like.
