Orange (colour)


 

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, yellowred, or yellored (all pronounced the same).
