+Enabling this option will cause PuTTY to ignore the configured colours
+for \q{Default Background/Foreground} and \q{Cursor Colour/Text} (see
+\k{config-colourcfg}), instead going with the system-wide defaults.
+
+Note that non-bold and bold text will be the same colour if this
+option is enabled. You might want to change to indicating bold text
+by font changes (see \k{config-boldcolour}).
