PROGRAM:
NAME
xcolors - display all X11 color names and colors
SYNOPSIS
xcolors [ -start color ] [ -near color ] [ -distance howfar ]
DESCRIPTION
xcolors reads the rgb.txt file that defines the color names the X server knows and
displays the colors found.
At the top of the window is a sample region containing text. By clicking on the color
names, the color of the sample text can be changed. Mouse button 1 changes the
foreground; button 2 changes the background. The text can also be edited.
Typing ``q'' exits the program.
OPTIONS
In addition the the usual X Toolkit options, xcolors understands these command line
options:
-start name
specify a color name to start with; colors before this one in the rgb.txt file are
skipped. This option is useful if there are more colors than will fit on your
screen or in your colormap.
-rgbfile filename
specify an alternate color database file to read.
-near nearcolor
only show colors near this one in the RGB space. All colors within a sphere in the
RGB-space centered on nearcolor are displayed.
-distance howfar
defines how close colors have to be to nearcolor to be displayed. This option sets
the radius of the sphere used by the -near option. The scale is such that the RGB
cube is 256 units on a side. The default is 64.
ACTIONS
set-foreground([color])
Set the foreground color of the sample region. If no color is provided, the color
is taken from the border color of the widget where the action occurred.
set-background([color])
Same as set-foreground() but sets the background color.
quit() Exit xcolors.
