# colrpick provides a command-level interface to the ColorDialog
# procedure. The ColorValue() of the selected color is written to
# standard output when the Okay button is pressed. If the Cancel
# button is pressed, colorpick exits with an error by calling stop().
#
# A default color can be specified by one or more command arguments,
# for example "colrpick deep green".
