I think you want to render some pieces of the list in black and the others in different color? It's HTML question then. And this stuff is not going to work:

<span class="someclass" color='somecolor'>Text</span>

Try:

$menu .= '<li><span class="'.$cls.'" style="color:"'.$clor.'">(the rest of your text here)</span>';

or

$menu .= '<li><span class="'.$cls.'" style="font-color:"'.$clor.'">(the rest of your text here)</span>';

If it solves your questions, you can look up some tutorials about CSS styles (hint: search for background-color, font-color, text-decoration, font-weight).
