This playful dragon is a bright, vibrant addition to any coloring page. Its scales are a deep green, while its belly is a light yellow. Its neck curves gracefully, while its head is tilted back in what looks like laughter. Its wings are outstretched, and its long tail is wrapped around its body. To bring out the details of the dragon, I would use a darker shade of green to outline its scales, a brighter yellow for its belly and a light pink for its wings and tail. This will create a more vivid picture and make the dragon come alive. For its eyes, you could use a light blue to easily differentiate them from its scales. I think it would look really great if you used a combination of light and dark shades for the rock it is sitting on. This will add texture and depth as well as creating a great background for your dragon.
