NAME
     rgb - build the color name database

SYNOPSIS
     /usr/bin/rgb [ dbname ]

DESCRIPTION
     rgb reads from standard input lines of the form:

          red  green  blue      name

     where red / green / blue  are  decimal  values  between  the
     range 0 to 255, and name is a description of the color.  rgb
     then builds a color name database in ndbm format.  The color
     name  database  provides a mapping between ASCII color names
     and RGB color values.  It is useful for increasing the  por-
     tability  of color programs.  The input source for the data-
     base is in /usr/lib/X11/rgb.txt.  rgb.txt is  compiled  into
     the  ndbm  files  rgb.dir  rgb.pag.   When  the server first
     starts up, it consults the contents of these files to  build
     an internal representation of their contents.  This internal
     representation is consulted to  map  color  names  to  color
     values.

     rgb   uses   the   default   color    name    database    of
     /usr/lib/X11/rgb.txt.

OPTIONS
     dbname    Color name database.

EXAMPLES
     example% rgb rgb < /usr/lib/X11/rgb.txt

                                   values.
