This Chameleon is perched atop a tree branch, its long tongue flicking out to grab a fly. Its body is covered in a dull green, while its back is speckled with patches of yellow and brown. Its large eyes bulge out of its head, and its head is also decorated with a spiky crest. To bring out the features of this Chameleon, I would suggest using contrasting colors to make the dark spots more noticeable. Shades of brown and yellow on the patches, and a light green for the body color to make the spots more defined. Then, use a darker shade of green for the head and back, and use a light blue or turquoise shade to contrast with the brown and yellow colors for the tongue and head crest. Finally, I'd use an even lighter shade of green for the eyes, which will make them stand out of the face of the Chameleon.
