.VERBON 22 16
\&.COLOR red "first argument is in red" ,
.VERBOFF
.COLOR red "first argument is in red" ,
and the optional second argument is in the current color.
.P
To set the foreground color at the start of the presentation, you
can use the macro INITCOLOR

To set the default foreground color for text, headers, and footers,
you can use the macro DEFAULTCOLOR

DEFAULTCOLOR and INITCOLOR should only be used after the definition
of the HEADER macro (if you use one).

You can also change the foreground color by embedding a
