Robin egg blue, also called eggshell blue or robin's-egg blue,^[1] 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.^[2]

The first recorded use of robin egg blue as a color name in English was in 1873,^[3] though earlier references in English to colors similar to that of robin's eggs were made as early as 1844.^[4] The "robin's egg" glaze appeared during the Yongzheng Emperor’s reign (1722-35) in China, and Yixing potter Hua Fengxiang made works with "robin's egg" glaze.^[5]
