History

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).

In painting

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

In computer CSS

It is the only named colour defined in CSS that is not also defined in HTML 4.01.

Variations of the colour orange

It is the same colour as the fruit for which it was named. So in contrast to Blue or Red this colour is well determined - we see the samples.

The colour orange is often used for visibility enhancement.

Orange pigments are largely in the ochre or cadmium families.

Brown is actually on the orange part (orange + grey) of the colour spectrum.

Burnt orange

Burnt orange is one variation that is used as a school colour of the University of Texas at Austin Longhorns as well as the newly established University of Johannesburg[link]. Here is a sample of burnt orange: [link]. Burnt orange can also be created using #CC5500. Variants of burnt orange are used as school colours at Auburn University, Clemson University, Virginia Tech, among others.
