Furthermore the pigment sepia, a beautiful brown color used historically in inks and paint, is derived by removing the ink sac from the cuttlefish (it shoots ink like a squid).

Although it has largely been replaced by synthetic alternatives, you can still obtain traditional sepia from places like Kremer's Pigments - which is a supplier of historic pigments, mediums, and recipes (used by conservationists and artists who like to make their own paint).

I find the brown color of the traditional sepia to be extremely beautiful, the dried pigment has an extremely pungent odor, quite similar to the dried squid you might find at your local Asian fish market.
