Scientists Create Computer Language to Describe Color
"We created a tool that is as natural and as easy to use as simply describing what you want to change," says Xerox color research scientist Karen Braun.

Xerox researchers have created Natural Language Color technology, a computer language that enables users to describe how they want an image's colors adjusted. The program translates over 65 keywords into algorithms to edit an image. The keywords were provided by test groups that used consistent vocabulary to describe colors.
Xerox researchers used colorimeters to assess a color and give it a number designating its brightness, darkness, or intensity. "Xerox performed thousands of experimental observations to ensure that the phrasing accurately adjusts the colors," says Xerox color research scientist Karen Braun. She says the "software can create over 50,000 possible color variations of the user's picture." Beyond offering a richer color palette, Natural Language Color technology can edit specific parts of an image without affecting the rest of it. "You shouldn't have to be a color scientist to get the right color where you want it," Braun says. "We created a tool that is as natural and as easy to use as simply describing what you want to change."
