A color display apparatus and method for displaying colors using radiation sources uses displays that may include multiple radiation sources, a display surface and control hardware and software that enable accurate and reproducible color display. Another apparatus provides means for generating colors upon request and communicating digital information regarding the generation of the color spectrum to local or remote display devices. The apparatus may be used in selecting and ordering colors subject to supplier constraints. Methods for displaying colors and enabling display of the colors in remote locations, as well as methods for conducting business by communicating the color display information are all provided.

Color display device

The method uses color to determine the wear of the screw and barrel of the molding machine. The method measures the color and/or color variation to determine the wear. A first material of a first color and a second material of a second color are fed into the machine to create a third material with a third color. The third material is either extruded to form a part or is injected into a mold to form a part. The color of the part is then measured with a measuring device, such as, spectrophotometer. The color will change as the screw and barrel wear. The color value would then be compared with previous color values to determine the amount of wear.
