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.

RESOURCES

       Xcolors has a few top-level application resources that allow customizations that are specific to xcolors.

       startColor (classStartColor)
              See the -start option.

       rgbFile (classRgbFile)
              See the -rgbfile option.

       nearColor (classNearColor)
              See the -near option.

       nearDistance (classNearDistance)
              See the -distance option.

WIDGET HIERARCHY

       Knowing  the  name  and  position in the hierarchy of each widget is useful when specifying resources for
       them.  In the chart below, the class and name of each widget is given.

       Xcolors xcolors
            Paned panes
                 AsciiText sample
                 Viewport viewport
                      Box colors
                           Label colorname
                           Label colorname
                           .
                           .
                           .

FILES

       /etc/X11/rgb.txt
              X color names and values.

BUGS

       Assumes that all names for the same color are consecutive in the rgb.txt file.

       Because xcolors cannot read the server's color name database, the color names it uses may not match those
       in the server.  This is most likely to happen if xcolors is run from a remote host.

       The program would be faster if it used gadgets instead of widgets for the color spots.
