Other forms: teals
Teal things are colored a deep shade of blue-green, like the sparkling teal water in a tropical lagoon. The color gets its name from a kind of duck, also called a teal.
The common teal is a migratory water bird, a duck with a teal stripe on its head and wings. The origin of the word is unclear, but we know the bird came first and then the color—the green-blue teal was first used in print in a 1923 clothing advertisement. It was added as an official color to the Plochere Color System, an interior design reference, in 1948, and became a Crayola crayon color in 1990.
