I'm in two minds about the colour schemes used on the Scouts. On one hand, it gives them a degree of consistency with the movie toys, since they're all primarily supposed to be real vehicles and thus mostly dull colours. They couldn't just reuse the colours for the originals-that would lead to them sticking out like a sore thumb.
On the other, the colour schemes don't work on all the toys. As I said in Air Raid's review, who needs jungle camo in space?
Overall, I like them, although I'm not really a fan of dull colour schemes.
