I've got quite a few years experience in auto painting so I'd like to consider myself at least a smidgeon qualified to throw in my .02 that any black vehicle (car, plane, boat, etc.), while quite pretty, only looks pretty for about a day after you wash it.
After the dust settles on it, it just looks ugly and dirty.
Also, black sucks up heat like no other color and the interior of anything black will be considerably hotter compared to anything of a lighter color. I wouldn't want my avionics to sit inside a black aircraft in direct sun for any length of time; they get hot enough already.
On the other hand, I haven't washed my silver Dodge Ram for at least 3 months and it still looks as clean as my neighbors car that he washed last weekend.
