1911 Encyclopædia Britannica/Auburn (colour)
Appearance
AUBURN (from the Low Lat. alburnus, whitish, light-coloured), ruddy-brown; the meaning has changed from the original one of brownish-white or light yellow (citrinus, in Promptorium Parvulorum), probably through the intensification of the idea of brown caused by the early spelling “abron” or “abrown.”
