+There are a limited number of function escapes to output terminal escape
+sequences. These sequences are retrieved from the
+.IR terminfo (5)

+argument, the color name, which can be one of: black, red, green, yellow,
+blue, magenta, cyan, white.  (\fIresetterm\fR\^) resets all terminal
+attributes back to their default setting.
