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.
