Origin: A blind person talking about colors is talking about something entirely outside their experience. The image of the blind trying to judge or guide what they cannot see is very old, from the Gospels' blind leading the blind to Horace's blind man who wants to show the way. The German phrase means talking confidently about something one knows nothing about; its first German use is not documented.
