<h3>
Description:
</h3>
This function generates a <em> VT100/ANSI</em> compatibel escape
sequence to change the output color. Regardless of the names
used here, the actual outcome is influenced by the terminal
itself: the terminal may have a visible bell, different
colors. The terminal can ignore certain combinations, refuse to
blink,  &hellip; .

The <tt> l</tt> argument contains strings of the following form:
<ul>
<li> <tt> "f_<em> color</tt>"</em> with <tt>\em color</tt> one of
<tt> black, red, green, brown, blue, magenta, cyan, white</tt>.
This defines the <em> foreground</em> color.
<li> <tt> "b_<em> color</tt>"</em> for the background color.
<li> <tt> "bright", "blink", "underscore", "reverse", "blank"</tt>
to set additional attributes.
<li> <tt> "bell"</tt> to include a terminal-bell.
</ul>

For example to produce red letters on a blue background, one should
use <tt> ColorString("f_red", "b_blue")</tt>. Depending on the
<em> termcap</em> entries and (eventually) the <tt> .Xresources</tt>.

To get yellow, one should use <tt> "brown"</tt> together with
<tt> "bright"</tt>.
