The jetpack troopers seem to be green on Kamino and blue on Naboo and Geonosis. Odd...
The scouts were originally going to be black, but then they decided to make them red. In that screenshot showing the black one, you can tell that it's an old outdated screenshot because there's still the clone officer (the yellow commander).
I don't know where you got red ARC Troopers as heavy weapons from... because the only screenshot I've seen of a heavy weapons ARC Trooper is of a blue one.
But anyway, I won't argue with you, because you're already right because you care more.
