      xcoloredit - find colour values by graphical colour mixing

      xcoloredit [ standard X Toolkit arguments ] [ -silent ] [ -format
      "format string" ] [ -text "example text" ][ {0-255} .. ]

      xcoloredit provides a graphical method of mixing the three primary
      colors available on a colour workstation.  This mixing can be done
      using the Red, Green and Blue slider controls on the left of the
      window or using the Hue, Saturation and Value slider controls on the

      The three boxes above the Red, Green and Blue slider controls are used
      for linking the controls together via the fourth slider to the right
      of the blue slider.  Whilst in the slider controls the first mouse
      button increments the colour components value, the third mouse button
      decrements the value (this only works with the Red, Green, Blue and
      Linked sliders).  The middle mouse button allows the user to
      continually change the value.

      The results of the colour mixing is shown in the four central squares.
      The three smaller squares showing the intensities of the red, green
      and blue components.  The hexidecimal value below these squares is the
      corresponding colour value which can be used in defaults files.  This
      value is also placed in the PRIMARY_COLOR selection property.  If the
      user presses the colour value button the button is highlighted and the
      colour value is placed in PRIMARY_SELECTION as well (useful for
      pasting into defaults files).

      At the bottom of the main window are 36 colour cells.  The current
      colour cell is highlighted by box drawn around it.  By clicking with
      the first mouse button in another cell this new cell's current value
      can be edited (if the cell has no defined value the current cells
      value is copied to it and the cell is highlighted with a dashed box).
      These colour cells can be connected to cells in the default colourmap
      of the display.  To do this the user must give the colourmap entry
      number(s) (pixel number) as a command line argument(s).

      The text shown in the mixed colour window can be displayed in one of
      the 36 colour cell colours.  Typing "c" or "t" in this window changes
      the colour of the text to that of the currently selected colour cell.
      This can be used to see what text will look like with different
      foreground and background colours.  The example text can be modified
      using the -text command line option.

      Apart from standard X Toolkit options, the following are available:

           Do not print out the edited colour values when xcoloredit quits.

      -text "example text"
           This sets the example text to display in the mixed colour window.
           Newlines are allowed in this string.

      -format "format string"
           This string is the format used to display the RGB value of the
           colour.  This format is used by the printf(2) function call.  By
           default the format is set to "#%02x%02x%02x" which is the
           standard RGB format for X.

      The following selection atoms are used/defined:
      PRIMARY_COLOR - current colour selection value
      PRIMARY_SELECTION - current colour selection value when highlighted.
