The huge dragon towers majestically atop the castle, its wings wide and proud. Its bright green scales contrast against the bright blue background, while its sharp claws and fiery eyes can be seen from the tallest of spaces. It is an imposing figure, an astute guardian protecting its people. To bring this creature to life, try coloring its scales in deep green with yellow and red stripes, while its claws and teeth might look brilliant in golden hues. Bring out its majestic wings with a brilliant blue and its fiery eyes with vibrant oranges. Finally, use soft pink tones to contrast against the strong colors of the dragon, adding a touch of whimsy and beauty to the scene.
