This valley is bursting with beauty. It is a bright white expanse, stretching out beneath the vast blue sky. A river cuts through the valley, running calmly along its winding course. In the distance, snow-capped mountains stand majestically against the backdrop of the horizon. To color this serene landscape, I would use shades of light blue and green for the sky and river, browns and tans for the mountains, and ivory whites for the valley. These cool hues will create a peaceful and refreshing effect, allowing the viewer to escape and relax in the beauty of nature.
