Why are lobster shells different colors?
Lobsters have different pigments in their shells – just like people have different pigments in their skin – and display a variety of colors. In Maine, there are blue lobsters, yellow lobsters, red lobsters, and even spotted lobsters. Usually, when lobsters are hard-shelled, their shells are a darker color. Also, when you cook hard-shell lobsters, their shells will turn a brick red color and sometimes even black, whereas soft-shelled lobsters, when cooked, are a bright red color.
