Is there a scientific reason why lobsters turn red after they are cooked?

Question

Just curious. Mature answers only please.

Answer 1

Live lobsters are usually bluish green in color. On rare occasions, one is landed that is orange, yellow, or blue. The lobster's color is caused by pigments in the shell. When the lobster is cooked, all of the color pigments are masked except the red background color.

Answer 2

The exoskeleton (shell) of the lobster contains a pigment called astaxanthin.  This pigment is attached to a protein called crustacyanin, and this complex is green.  When boiled, the astaxanthin is released, and in this free form is red.
