colorview(1)

NAME
     colorview - display list of X11 colors and show selected color

SYNOPSIS
     colorview [ -browse ] [ -display dpy ] [ -geometry geom ]
               [ -name name ] [ -text ] [ file | - ]

DESCRIPTION
     Colorview is an X11 program that displays a color ``patch'' and a list of
     color names from an X11 rgb database. The color for a name is displayed
     by clicking the left mouse button over the color name.

     Command-line arguments are:

     -browse   only lists the colors; the Accept and Apply buttons are not
               displayed.

     -display dpy
               specifies the X server to contact; see X(1).

     -geometry geom
               specifies the preferred size and position of the window; see
               X(1).

     -name name
               specifies the application name under which resources are to be
               obtained, rather than the default executable file name.

     -text     indicates the specified file is a text file containing color
               names and/or X #rgb color specifications, with 1 name per line.

     file      specifies the name the rgb database. The database must be in
               ndbm(3B) format unless -text is specified.  With -text, the
               database is read from standard input if file is ``-''.

     Colorview has three buttons when not invoked with -browse:

     Accept    Print the selected color name on the standard output and exit.

     Apply     Print the selected color name on the standard output.

     Cancel    Exits the program.

EXAMPLES
     To display only unique colors from the default rgb database:

          showrgb | sort -u +0 -3 | awk '{print $4,$5,$6,$7}' \
              | sort | colorview -text -
     To display a list of colors from a file:

          colorview -text mycolors.txt


     To display a list of colors using the X #rgb color specification:

          colorview -text - << _END_
          #f0f
          #7171c6
          #8E3855
          _END_
