Harlequin is an adjective that means of varied colors.
Based on an obsolete French word, harlequin got its name from the leader of a legendary troop of demon horsemen. Soon it became a name used for a character in traditional pantomime. A harlequin was usually masked and dressed in a diamond-patterned costume. Its flamboyant, colorful costume gave birth to the word harlequin as an adjective that means ‘in varied colors.’
My daughter loves to decorate things wildly and flamboyant. So when I tasked her with painting the doghouse, she came up with a lovely, harlequin scheme.
