Valley is a lush landscape, beautifully shaded in green. A meandering river is snaking its way through the scene, its waters sparkling in the bright, blue sky. Far in the distance, snow-capped mountains can be seen, casting an ever-watchful eye over this idyllic place. To color this picture, I would focus on the contrast between the green fields, the clear blue sky and the white peaks of the mountains. I would pick a cool tone of blue for the sky and add shades of yellow and orange to the sunshine. The river could be highlighted with highlights of blues and greens, while using purples and yellows to accentuate the hills and valleys. To create depth, I'd place a few patches of colorful wildflowers scattered in the fields and add some wispy white clouds in the sky. Finally, I'd sprinkle a few dark greens in the shadows for a sense of realism.
