This coloring page has two alligators in it. The larger one is at the center of the page, and it is a bright green color. Its mouth is wide open, and its teeth are sharp and bared. Its eyes are fierce and seemingly predatory. In the bottom left corner, there is a smaller alligator that is brown. Its mouth is also wide open, and its teeth are sharp.
I would color the larger alligator in a dark green and then layer lighter shades of green on top to give it a more natural look. For the small alligator, I would color it a darker brown and then add a few lighter shades of brown for some added detail. To finish it off, I would add some white highlights to create a more realistic look for both of the alligators.
