Xerox Scientists Develop 'Color Language' to Get the Precise Color

Making color more usable ...

"Xerox Corp. announced that scientists are developing a new technology to make adjusting colors in a document as easy as simply describing the color. Users can type "make the sky a deeper blue" or give a voice command "make the background carnation pink" and the software does the work.

The invention, still in the research stage, creates "color language" by translating human descriptions of color into the precise numerical codes that machines use to print color documents.

"Today, especially in the office environment, there are many non-experts who know how they would like color to appear, but have no idea how to manipulate the color to get what they want," said Geoffrey Woolfe, principal scientist in the Xerox Innovation Group. "You shouldn't have to be a color expert to make the sky a deeper blue or add a bit of yellow to a sunset."

Yesterday, at the 2007 Annual Meeting of the Inter-Society Color Council (ISCC), Woolfe described his work in a paper called "Natural Language Color Editing." Xerox has filed for patents on the technology.

Xerox said Woolfe's discovery means that color adjustments could be made on devices like color office printers and commercial presses without having to deal with the mathematics. For instance, cardinal red on a printer or monitor is really expressed by a set of mathematical coordinates that identify a specific region in a three-dimensional space, which is the gamut of all the colors that the device can display or print. To make that color less orange, the color expert distorts (morphs) that region to a new region in the gamut.

The ability to use common words to adjust color would have far-reaching implications for non-experts as well as graphic artists, printers, photographers and other professionals who spend a significant amount of time fine tuning the colors in documents."    (Continued via IT News Online)    [Usability Resources]
