The Japanese name "真鴨色" (magamo-iro, "mallard color") is a deep blue-green seen on wild ducks' heads and necks. Another color name, "鴨の羽色" (duck feather color, #00688b), has the same meaning — though whether they are identical or distinct remains unclear. English equivalents include Teal Green (green-dominant) and Teal Blue (blue-dominant).
