Color described in the language of silence. Daniel Defoe's Captain Singleton (1720) paints a ship's stern "a dumb white or dun color," a white with no brightness in it. One root proposed for the word meant "darken, obscure," and if that account is right, this rare sense echoes the word's distant origins.

Origins
From Middle English and Old English 'dumb', meaning silent, mute, or unable to speak, going back to Proto-Germanic *dumbaz ('dull, dumb') and a Proto-Indo-European root. The senses of 'stupid' and 'pointless', regular only since the 19th century, probably developed under the influence of German 'dumm' and Dutch 'dom', which also originally meant 'lacking the power of speech'. It is cognate with Dutch 'dom', German 'dumm', and Swedish 'dum'.
