In the scene, a solitary sailboat drifts on the peaceful water. The shape of the hull is a bright white, in contrast to the dark mahogany of the mast. A buoy in the foreground adds an extra layer of interest. To recreate this nautical scene with color, I would suggest a light blue for the water and a sandy yellow for the buoy. A soft grey for the sides of the sailboat would greatly enhance the white of the hull. For the mast and the buoy, trying shading from the darkest brown up to beige could give the piece a more realistic look. Finish with some texture in the sails for more appeal. Let your creativity sail away!
