See also Orange (disambiguation) for other meanings of the word.

The colour orange occurs between red and yellow in the visible spectrum at a wavelength of about 620-585 nanometres. It is the same colour as the fruit for which it was named. Before the orange fruit was introduced to the English-speaking world, the color was refered to (in Old English) as geoluhread, which transliterates into Modern English variously as yellow-red or yellored (pronounced the same).

With natural colouring materials such as paints or crayons, orange or "yellored" is a secondary colour that can be derived from primary colours by mixing red and yellow.
