Sarnoff, Algen Develop New LED-Based Color Visualization System for Precise Color Matching and Communications.Business Editors & High Tech Writers PRINCETON, N.J./EATONTOWN, N.J.--(BUSINESS WIRE)-- Aug. 21, 2002 Coloron(tm) System Shares Product or Design Color Information Electronically; Eliminates Differences in Viewer Perceptions Sarnoff Corporation Sarnoff Corporation, with headquarters in Princeton, New Jersey, is the former RCA Laboratories. The headquarters is the site of the development of color television, CMOS technology, electron microscopy, and many other important technologies since the cornerstone was laid just , the Princeton-based technology developer, and Algen Design Services, the Eatontown-based electronics design and manufacturing company, have developed and patented Coloron(tm), an electronic color visualization system that allows product designers and companies who manufacture or work with colored products to accurately create and compare colors locally and remotely via the Internet. Coloron significantly minimizes problems caused by differences in human color perception and limitations associated with conventional CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. or LCD displays. Algen and Sarnoff have built several generations of pre-production prototypes (photo at www.sarnoff.com/consumer_electronics/coloron/) and are seeking partners to bring the Coloron color communication system to market. "Coloron will revolutionize how people analyze and communicate color," said Ralph Stanziola, an industry expert who consulted on the creation of Coloron. "With Coloron a color specifier and the manufacturer of colored not of the white race; - commonly meaning, esp. in the United States, of negro blood, pure or mixed. See also: Color material can communicate the desired color without sending all or most of the physical samples they now use. And since Coloron has a color gamut The entire range of colors available on a particular device such as a monitor or printer. A monitor, which displays RGB signals, typically has a greater color gamut than a printer, which uses CMYK inks. greater than twice that of conventional CRTs, it can accurately display colors of dyed or pigmented products that cannot be duplicated on a CRT . "We've needed this system for years and now Sarnoff and Algen have demonstrated its feasibility." More Colors, Higher Accuracy, Internet Speed Using a standard personal computer, Coloron generates the actual color display on a separate device using multiple light-emitting diodes (LEDs). The color is presented on a square surface that acts as an electronic "color chip." This LED-based display can provide a much greater range of colors than a standard computer monitor. The approach also allows viewers to perceive colors with greatly improved precision and repeat ability. Because standard display technology attempts to match all colors by mixing only red, green, and blue on a CRT or LCD monitor A flat panel display that uses liquid crystals. Although laptops have used LCDs as their flat panel technology almost exclusively, LCD is also the most popular for flat panel desktop monitors. Toward the end of 2003, sales of LCD displays for desktops overtook CRTs for the first time. , there can be significant viewer metamerism The quality of some colors that causes them to appear differently under different light sources. For example, two color samples might appear the same in natural light, but not in artificial light. when the monitor color is compared to real dyed or pigmented samples. Metamerism is a condition in which different people comparing color samples perceive the matches differently, usually due to the aging of the eyes. Coloron's use of many narrow-band light sources eliminates or significantly minimizes metamerism, allowing displayed colors to be compared to real dyed or pigmented samples with high accuracy and a high level of agreement among viewers. Coloron also generates a spectrophotometric curve corresponding to the displayed color, enabling higher color reproducible in the final product. Manufacturers can use the spectral data to reproduce the color of the display on their dyed or pigmented material more precisely. In addition, since the color information is electronic form, it can be stored on a disk or networked to other Coloron users. This makes it possible to quickly disseminate color choices for review, approval, formulating or matching to a color in Verb 1. color in - add color to; "The child colored the drawings"; "Fall colored the trees"; "colorize black and white film" color, colorise, colorize, colour in, colourise, colourize, colour a database. Other features include the ability to view two or more colors side-by-side, to program textures onto the colors, to view the display under ambient lighting Light that comes from all directions. Contrast with "directional lighting," which is made up of a light source with parallel light rays that do not diminish with distance. Also, contrast with "positional lighting," in which the rays are not parallel, but diminish in intensity from the conditions, and to use Coloron in a light booth where samples can be compared under such varied sources as daylight, incandescent in·can·des·cent adj. 1.
