XCOLORS(1)		    General Commands Manual		    XCOLORS(1)

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	click-
       ing  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  col-
	      ormap.

       -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  dis-
	      played.

       -distance howfar
	      defines  how  close  colors  have	 to be to nearcolor to be dis-
	      played.  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 customiza-
       tions 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
       /usr/X11/lib/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.
