Burnt orange has been in use as a colour name for this deep shade of orange since 1915.[8]

This colour is one variation that is used as a school colour of the University of Texas at Austin, Westwood High School (Austin, Texas), Clemson University, Virginia Tech, Auburn University, and Mesa Verde High School (Citrus Heights, California).

This variation of orange is one of the primary colours for the American Football team the Cleveland Browns. Burnt orange was popular in interior design during the 1970s, and is often associated with this period. Red headed peoples usually have hair that is more accurately a burnt orange colour.


Brown is actually derived from the orange part (orange + grey) of the colour spectrum. It can be described as an especially dark orange.

The first recorded use of brown as a colour name in English was in about 1000 in the Metres of Boethius.[9][10]
