I doubt mother nature would have such a clean division of the sides.
Most lobsters are colored a mottled dark greenish brown. In rare cases, a lobster of a different color (colormorph) appears. Exotic lobsters in shades of blue, white, yellow, black, and red have been reported from time to time since the earliest lobster harvests. Perhaps the most unusual colormorphs are the "calico" lobsters appearing as marbled black and orange/yellow; or "half-and-half" lobsters with a line straight down their backs where two colors meet.
Calicos and half-and-halfs are hatched that way and they stay that way (until cooked!) because the basic color pattern in lobster shells is inherited just like the color of hair in humans and other mammals.
However, some of the blue, brown, green, red, and black tones can be genetic or they can have other causes. In some instances lighter/darker shades can be influenced by diet, sunlight, and bottom type. For example, if you put a blue lobster in a holding system and its color becomes normal over a period of time, that lobster is undoubtedly not a 'igenetic blue." It was probably blue as a result of a dietary deficiency.
Lobsters get their characteristic color, not only from genctics, but, also from the foods they eat. A natural-colored lobster fed a diet of squid will turn blue. A lobster deprived of all prey that eat phytoplankton (floating plantlike critters) appears pale blue.
There are always stories about people "from away" who, accustomed to seeing their lobsters cooked, are horrified by the color of a living lobster. They are sure it must be moldy. A live lobster is greenish-black on top and orange below, with accents of blue on the joints of its claws. That is because a lobster's shell is composed of three pigments: red, blue, and yellow.
When one or more of these pigments are missing at birth, a lobster may be red, blue, albino (white), or calico (dark with yellow spots). Blue lobsters occur once in every 3-4 million lobsters. Red lobsters (live ones) occur once in every 10 million. Except for albinos, all the color variations of lobsters turn red when they are cooked.

hey, naysayers -
"nature never draws a straight line"
a proven fallacy.
This lobster, though, has no blue in half of its shell, she said.
Bernard Arseneau, a former manager at the oceanarium's lobster hatchery, said lobsters also have a growth pattern in which the two sides develop independently of each other.
