Which artist invented and patented a color?

In 1960, Klein created and patented the ultramarine color known as International Klein Blue or IKB. He invented the paint with the help of a chemical retailer by suspending pure, dry pigment in crystal-clear synthetic resin and compatible solvents. Unlike traditional binders, the new colorless carrier did not dull the individual particles of pigment, but left them with their original brightness and intensity.
