Here in Oregon, where there is often white overcast and snow in the
mountains in the winter, there's a lot of white. It seems to me that
painting your aircraft white is akin to camoflage. Wouldn't it be better
if
airplanes were missile red, cub yellow, construction orange or some other
extremely-visible color?

Perhaps a better question is, why are most homebuilts white with trim? I
know the composite aircraft basically require it, but I see so many RV's out
there in the same boring-white-with-trim... standardization certainly isn't
an issue with them...

However, there's a G-200 out there with that color-changing paint...
