Heritage
Teal — the blue-green range — is named after the Eurasian teal duck, which has a stripe of this color on its head. Egyptian blue and Egyptian green, both copper-based pigments, flank this region. The patina of weathered copper (the Statue of Liberty's color) sits here too; on the statue it is mostly basic copper sulfate. Phthalo turquoise is a 20th-century pigment.
