A beautiful scene of two bottlenose dolphins swimming alongside each other is depicted in this coloring page. The one on the left is long and slender, with a slender nose, while the one on the right is wider, with a shorter nose. Both dolphins are a warm, slate gray color with white spots, and have their mouths wide open as if they are enjoying the moment. To color this image, I would recommend using shades of light and dark blues, whites, and grays to contrast the two dolphins, while keeping some warm tones to give the sense of a peaceful ocean experience. You could also use bright, vibrant colors to create contrast and draw the eye to the two swimming dolphins.
