Tawny is a yellowish brown color. The word means “tan-colored,” from Anglo-French tauné “associated with the brownish-yellow of tanned leather,” from Old French tané “to tan hides,” from Medieval Latin tannare from tannum “crushed oak bark,” used in tanning leather, probably from a Celtic source (e.g. Breton tann “oak tree”).
