Orange (colour)

For other uses, see Orange (disambiguation).

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 colour was referred 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.

This is the only named color defined in CSS that is not also defined in HTML 4.01.
