   --color=WHENCOLOR   ``clush`` can use NO_COLOR, CLICOLOR and CLICOLOR_FORCE environment variables. NO_COLOR takes precedence over CLICOLOR_FORCE which takes precedence over CLICOLOR.  When ``--color`` option is used these environment variables are not taken into account. ``--color`` tells whether to use ANSI colors to surround node or nodeset prefix/header with escape sequences to display them in color on the terminal. *WHENCOLOR* is ``never``, ``always`` or ``auto`` (which use color if standard output/error refer to a terminal). Colors are set to [34m (blue foreground text) for stdout and [31m (red foreground text) for stderr, and cannot be modified.
