Buff (colour) Buff (colour) Buff is the pale orange-brown colour of the undyed leather of several animals. As an RYB quaternary colour, it is the colour produced by an equal mix of the tertiary colours citron and russet. The first recorded use of the word "buff" to describe a colour was in "The London Gazette" of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he
Indexed color 1980s by the more flexible RGB color model, in which a given color can be obtained by mixing different amounts of the three primary colors red, green, and blue. Although the total number of different colors depends on the number of levels per primary, and on a given hardware implementation (a 9-bit RGB provides 512 combinations, a 12-bit RGB provides 4,096, and so on), in this model Digital-to-Analog Converters (DAC) can generate the colors — simplifying the hardware design — while the software can treat the number per levels used abstractly and manage the RGB colors in a device-independent fashion.
