MCOLOR(7)			Macro Packages			     MCOLOR(7)

NAME
       mcolor - color and reverse video macro

SYNOPSIS
       troff -mcolor [ options ] file ...

DESCRIPTION
       mcolor  is a macro package for color selection and reverse video print‐
       ing on PostScript printers.  The package is compatible with most exist‐
       ing macro packages and includes the following macro:

       .CL color text
		   Prints  text	 in  color.  No arguments restores the default
		   color (black in RGB color space).  If text is  omitted  the
		   selected  color  remains  in	 effect until another color is
		   selected.  If two arguments are given the text  is  printed
		   in color and then the default color is restored.

       Both  the  text and background color can be selected.  A color argument
       of ``color1 on color2'' prints text in color1 on a background in color2
       .

       Once a color is in effect, it is re-installed at the top of each output
       page.

       Arbitrary PostScript color parameters can be set by using  color	 argu‐
       ments like

	      red green blue rgb
		     e.g. `.CL ".2 .3 .4 rgb"'
	      hue saturation brightness hsb
		     e.g. `.CL ".5 .6 .7 hsb"'
	      cyan magenta yellow black cmyk
		     e.g. `.CL ".1 .2 .3 .4 cmyk"'
	      gray setgray
		     e.g. `.CL ".5 setgray"'
	      [$setcolorspace] comp1 comp2 ... compn setcolor
		     where   $setcolorspace  may  be  a	 PostScript  procedure
		     defined in the setup section using a  `\X´PSSetup:	 $set‐
		     colorspace	 {  ...	 }  bind  def´' escape sequence.  This
		     parameter is required if the color space changes  in  the
		     document.	Otherwise, it may be sufficient to install the
		     color space once in the setup section.

       Each parameter must be a number in the range between 0.0 and  1.0.   In
       the  most general case, the value of the color argument is passed unin‐
       terpreted to the PostScript output.

       Named colors (RGB only) must be listed in the ``colordict''  dictionary
       in file /usr/ucblib/doctools/font/devpost/postscript/color.ps.

NOTES
       Use  of	the .CL macro is not always appropriate since it may (as every
       macro) result in added spaces.  The \X´SetColor:	 color´	 can  also  be
       used  directly  to  avoid this; its color argument has exactly the same
       syntax as the first argument to .CL, e.g. `\X´SetColor: .2 .3 .4 rgb´'.
