The vast, empty valley lies between two looming mountains. The center of the valley is filled with a babbling stream and a small waterfall tumbling down into a peaceful pool below. On the far side of the valley lies a thick, lush forest with a tiny clearing in its center, with a solitary tree at its epicenter. A small orange robot stands next to the tree, next to a white robot, both of them facing a small blue robot.
To color this scene, the valley could be a light or pastel green, while the mountains a grayish hue or blue. The stream flowing down from the waterfall could be given a brighter blue, with the waterfall itself a lighter blue or white. The trees in the forest could be a dark green, with the clearing a lighter green. The robots would need to be bright pops of color - the orange robot a bright yellow-orange, the white robot pure white, and the small blue robot a royal blue. Finally, the tree in the center of the clearing could be a rich brown.
