You can choose from several color models and from a number of color matching systems when you create colors. If you have colors you use frequently, you can create colors for the default color list in the application when no files are open. You can create up to 1,000 default or article-specific colors. To create a color, choose Edit > Colors to display the Colors dialog box, and click New to display the Edit Color dialog box. Then, enter a name in the Name field and specify the color model for your new color.

• RGB: This additive color system is most often used with slide recorders or color video monitors, and also works well for Web pages. Red, green, and blue light is mixed to represent colors on a video screen.
• HSB: This color model is often used by artists because it resembles the manner in which they mix colors. Hue describes color pigment; saturation measures the amount of color pigment; and brightness measures the amount of black in a color.
• LAB: This color space is designed to be independent of differing interpretations imposed by monitor or printer manufacturers. The LAB color model, also referred to as LAB color space, is a standard three-dimensional model for representing colors. Colors are specified by a luminance coordinate (L) and two chrominance coordinates (A for green-red), and (B for blue-yellow).
• Multi-Ink: This color model is color based on tint percentages of existing process or spot inks.
• CMYK: CMYK is a subtractive color model used by professional printers to reproduce colors by combining cyan, magenta, yellow, and black inks on a press.
• Web Safe or Web Named Colors: Web-safe colors are used for color consistency in Web layouts.
• To select a color from a color matching system and add it to your color list, choose one of the standardized color matching systems from the Model drop-down menu.
