All cats are gray at night

Meaning: When darkness obscures differences, all things appear equal or indistinguishable.

Origin: John Heywood's 1546 collection has "When all candles be out, all cats be grey" — in the dark, differences of color vanish. It was often said with a wink, to suggest that looks matter little by night, and the same saying exists in French, German and Spanish.
