Drab is a dull, light-brown color. It originally took its name from a fabric of the same color made of undyed, homespun wool. The word was first used in English in the mid-16th century. It probably originated from the Old French word drap, which meant cloth. The word gradually came to mean dull, lifeless, or monotonous.
