Why did my lobster turn blue?

MICHAEL TLUSTY: So when the lobsters eat the astaxanthin, the red pigment goes it into the skin, and that's where it shows up as being red. Then, the pigment gets moved up into the shell. And when it stores it in the shell, proteins grab the pigments and twist it around, and it actually turns to a blue color.
