Chromatophore

Chromatophore: A pigment-bearing cell found in some fish, reptiles, cephalopods, and other animals.

From Greek χρωμα (color) φέρειν (to carry). 

Remember this guy from Tangled?

Pascal

He could change the color of his skin since his skin contained chromatophores.  Or, maybe it was just because he was animated.  Still, he based on an animal whose skin contained chromatophores.  This makes him an animatichromatophore.  Which scares me.
