What's the difference between pigment and sepia?

Pigment


Definition:

  • (n.) Any material from which a dye, a paint, or the like, may be prepared; particularly, the refined and purified coloring matter ready for mixing with an appropriate vehicle.

Sepia


Definition:

  • (n.) The common European cuttlefish.
  • (n.) A genus comprising the common cuttlefish and numerous similar species. See Illustr. under Cuttlefish.
  • (n.) A pigment prepared from the ink, or black secretion, of the sepia, or cuttlefish. Treated with caustic potash, it has a rich brown color; and this mixed with a red forms Roman sepia. Cf. India ink, under India.
  • (a.) Of a dark brown color, with a little red in its composition; also, made of, or done in, sepia.

Example Sentences:
