Seeing how Dollywood has basically cut down all trees around terrain rides, I wonder what's the point of having this coaster going around the gentle slopes of the area without any trees that give a sense of speed and adventure into the forest. It is going to look bare...
As for the colour scheme, I have seen more offensive examples (looking at you I305). Some parks seem to be keen on exploring new colours schemes that oddly work (Alpengeist or Shambhala come to mind), but this one is just fine without being overly inventive/striking.
