The pigment orange

Orange


How the color got its name

The color we now know as to be orange was called "geoluhread" an Old English term which means "yellow-red". It is a very important color. This is because it is used on traffic cones.

How it's made:


Turmeric:


Although the site I used, doesn't mention this spice, my grandmother (who grew up in India) told me that they used turmeric in their orange dyes

Chrome Orange:
 This orange became used as a pigment in the year 1809 the color ranges from light to deep oranges, and the hiding power is excellent. You need the chemicals Lead(II) nitratepotassium dichromate, and sodium hydroxide to make this pigment.
The scientist Nicolas Louis Vauquelin noticed that the new element chromium produced a bright orange color. This color stopped being produced a few years ago.
Realgar:
Realgar is a HIGHLY TOXIC arsenic sulfide and it was the first pure orange pigment.
It was used in paintings until the early 1800's, when Chrome Orange came around.
