How do cuttlefish use chromatophores?

How do cuttlefish use chromatophores?

Cephalopods control camouflage by the direct action of their brain onto specialized skin cells called chromatophores, that act as biological color “pixels” on a soft skin display. Cuttlefish possess up to millions of chromatophores, each of which can be expanded and contracted to produce local changes in skin contrast.

How do cuttlefish work?
