Color Chooser
The Color Chooser is a tool which allows you so select precise colors for text and backgrounds. The simplest way to pick a color with the Color Chooser is to click the desired color in the multi-colored grid. This palette of 216 colors conforms to what is known as the Uniform Color Palette. In short, these colors are most likely to be rendered by all Web browsers in a uniform way. Every color can broken up into portions of red, green, and blue. This method of describing a color is known as the RGB color model. When you pick a color from the color grid its RGB value is shown in the window underneath the grid. This value is a hexadecimal number; that is, a number whose digits range from 0 to 15 (0-9,A-F). Two digits are used for each of the three RGB components for a total of six digits. The value 000000 is black and the value FFFFFF is white. By allowing you to enter RGB values directly the Color Chooser offers a total 16,777,216 possible color choices.
In some cases the color you are selecting will have a default value (as in the case of text color). The Page Colors topic describes the various default colors which can be established for a page. If you are choosing a color for a text field, the Color Chooser will offer an option under the RGB window to use the page color. When clicked, this option will clear any override chosen for the field in favor of the default color.
