7 . \" $1=red green blue rgb (e.g. .CL ".2 .3 .4 rgb") or

11 . \" If no arguments are given the default color (usually black) will be
12 . \" restored. If $2 is omitted the color selected by $1 remains in effect
13 . \" until another color is selected. If two arguments are given $2 will be
14 . \" printed in color $1 and then the default color will be restored.
16 . \" The color of the text and the background can be selected by setting $1
17 . \" to "textcolor on backgroundcolor" where textcolor and backgroundcolor
18 . \" can be any of the known colors. For example use .CL "white on black"
19 . \" for reverse video printing. Changing color in a word can be accomplished
20 . \" by preceeding the characters with a \X'SetColor:val' command, where val
21 . \" is the color you wish to use. Named colors are case independent.
23 . \" Implementation details are device dependent and are handled in the
24 . \" appropriate post-processor. Requesting a color that's not available
25 . \" (eg. not defined in /usr/lib/postscript/color.ps) results in the use
26 . \" of default colors - black or white on black for reverse video mode.
28 . \" All colors may not be supported on every output device, and the direct
29 . \" specification of a color via an explicit rgb or hsb argument may also
30 . \" be device dependent. In any case, to be safe on PostScript devices, all
31 . \" numeric paramenters in the direct rgb or hsb specifications should lie
32 . \" between 0 and 1 (inclusive). The names of the currently available colors
33 . \" on PostScript printers are listed in file /usr/lib/postscript/color.ps.
