What color is Harry's "blue" beetle?
Answer: Powder blue, white, yellow, red, green, and primer grey
I found 3 quotes for this (Thanks, Priscellie for pointing me to FM!):
Fool MoonThe Beetle wasn't really blue, not anymore. One of the doors had been replaced with a green duplicate, the other one with white, when something with claws had shredded the originals. The hood had been slagged by fire, and my mechanic, Mike, had replaced it with the hood from a red vehicle.
Dead BeatThe car has had various doors and panels replaced with white, yellow, red, and green. My mechanic, Mike, had managed to pound the hood more or less back into its original condition, which I’d bent our of shape while ramming a bad guy, but I hadn’t had the money to repaint, so now the car had primer grey added to its ensemble.
Proven GuiltyIt’s a jumble of different colors, as my mechanic has replaced damaged portions of the body with parts from junked Bugs, but it started off as a shade of powder blue, and that had earned it the sobriquet of the Blue Beetle.
ETA quote from PG, to clarify that the "blue" is "powder blue," 'cause it's a fine piece of trivia
