If I understand the script correctly, what it will be doing at the moment is setting the font colour to red, instead of the background colour. To do this, you'd normally have to sent the attribute on the <td bgcolor='red'>, rather than using <font
color='red'>, but you might try using a span instead.
$g2 = $g2 -replace "#font","<span style='background-color:red;'>"
$g2 = $g2 -replace "font#","</span>"
If this isn't what you're looking for (because there may be an untidy margin around the span, or something), you'll need to give the <td> a classname, and then change the css for that class within $b instead. Let me know if you prefer to try that.
