I was part of this discussion on another place, with a face and a thumbs up,,
ONe person contended that making the plane red made it harder to see accuratly and by that he felt you would score better because benefit of the doubt or something, never really got full grasp of his point.
There is some truth that maroon is harder to track than other colors,
then another poster of some acclaim commented that he painted his airplanes to be as visible as possble, contending that dark planes by capable pilots versus bright planes by the same pilots tend not to score as well, my take, because bright planes are easier to track and judge ,,
I love bright colors so it matters not to me, but even bright colors like my Green pearl beast could get lost at dusk wth trees behind it, and it was NOT even close to leaf green, it just disapeared, however so did every other airplane flown on that particular night,,
I have to agree with Brett here, ( and I did not see hm taking it personal at all, just reporting the facts as he sees them) if you can get in one quality pracitve flight in the time you spend thinking about this, you are probably better off flying, or building.
However that said, some of us do enjoy the mental gymnastics of this sort of thing when we cannot be building or flying, just please, dont let it dictate your enjoyment or advancment, build straight, practice ( quality practice, dont just fly) practice more, and paint the plane the way you want. When you need another half a point, then think about color ok?
