It looks like it's an aquatic based creature, so why not pick some colors that catch your eye from the ocean? If it's a deep sea or swampish inspired creature, it would probably be dark, and maybe even have some bioluminescence going on. Probably like midnight blue or a dark muddy brownish color with bright hilighted areas. If it's more of a surface ocean thing, it would most likely be vivid colors to catch the eye of its prey, such as coral pink with bright red or orange hilights.
