The Colors dialog box lets you create, edit, and delete color definitions.
Creating a color
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. You can also click the
New button on the Colors palette to create colors.
• 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).
