Why prawns and lobster colour changes into orange after cooking?

The pink or red color is the pigment Astaxanthin, but its molecules are wrapped up in dark protein chains. The shells are dark green or gray to start with. Whenever you cook a protein, it uncoils, or denatures. In the case of certain shellfish, cooking frees the red pigment and the shell changes color.
