Eggshell Blue

Robin egg blue

Robin egg blue, also called eggshell blue or robin's-egg blue, is a shade of cyan, approximating the shade of the eggs laid by the American robin, an abundant songbird of North America. The egg pigment is biliverdin, a product of the breakdown of heme.

Eggshell

An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer cots.

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
