This section describes documents (i.e., sub-windows in GNOME Color Browser window) showing some palette. A palette is just a list of colors, each one given a name. For example, X Window System comes with pre-defined system palette, containing hundreds of colors, from simple ones such as "red" or "blue" to exotic ones such as "LavenderBlush". You can also define your own palette, or several of them, as described below. Each palette is saved as a separate file; for example, the sytem palette is defined by the file rgb.txt, located in X11 library directory, usually /usr/lib/X11R6/lib/X11).
GNOME Color Browser can show a palette in two ways:
In this mode, GNOME Color Browser lists all colors in a palette, showing a small sample, Red, Green and Blue (RGB) values and name for each color (see the section called Colors in X Window System for detailed information about RGB values).
By default, the colors are listed in the same order in which they appear in the file, which is indicated by a small downward triangle next to the label Color. As with all GNOME applications, you can reverse the order by clicking on the word Color once. You can also have the list ordered alphabetically by name by clicking on Name label.
You can change the default width of Value and Name fields by dragging the separator between these fields with the left mouse button.
In this mode, GNOME Color Browser just shows a small sample for each color in the palette:
Regardless of the view you use, you can drag any of the color sample rectangles to GNOME Panel, GNOME Terminal, and many other GNOME applications windows to change their background colors.
In addition to system colors which an ordinary user can not change, you can also create your own color lists. To do so, select FileOpen and enter the name you want for your list (for example, favorites.txt). This will add to one more window to GNOME Color Browser, with tab name corresponding to the name of the file. Originally this window is empty; you can add any colors to it by FIXME
Once you have created your own palettes, you can add and remove colors to them, change palettes' name etc. Note that unless you are logged in as system administrator (root), you can not change system palette.
To add a new color to a palette, right-click anywhere in the palette and select New color from the pop-up menu, or select New color from the Edit menu.
To remove a color from the palette, select this color by clicking on it and select EditRemove selected colors. An easier way of removing a color is to right-click on it and select Remove selected colors from the pop-up menu. In the same way, you can select several colors and remove them all: to do so, click on the colors you want to select while pressing CTRL key. You can also select a continuous block of colors by clicking on the first color, and then clicking on the last color of the block while pressing SHIFT key.
Finally, you can cahnge other proeperties of the document, such as the name and format used by selecting Properties from Edit or pop-up menus. This will launch Properties dialog, described in the section called Properties dialog.
After modifying a palette, you can save your cahnges by selecting FileSave. You can also change modified palette under a new name by using Save as... command.
To change a color in a palette, select it by clicking on it and select EditEdit selected color, or just right click on the color and select Edit selected color form the pop-up menu.
