Robin egg blue

Robin egg blue, also called eggshell blue or robin's-egg blue, is a shade of teal (a blue-green color), 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.

The first recorded use of robin egg blue as a color name in English was in 1873, though earlier references to colors similar to that of robin's eggs were made as early as 1844.
