Very happy you got it in the air, thats great news. About the color, man, there isnt really a magic scheme that will look significantly better than the other, specially when far out. The F-16 will always dissapear for a fraction of a second when turning towards or away from you far away.....you will get used to it eventually. Sometimes I can only see a tiny spot, but I can tell what the spot is doing.
That being said, I think my favorite color was a Moroccan Camo a friend did for me (looks like an Israeli camo). It stood out very well when the model was near, but really made no difference when it was far. They all look black/dark gray when far out! :-)
Again congrats on your Viper, it will quickly grow into you and you will love it.
