Multiple Styles in Site Title

Hi

I'd like our site title to have the first word in bold:

SITE TITLE

Is this possible? I assume it's going to take some javascript of some sort because I'm pretty sure there's no CSS solution. Unless I can add an extra <span> or <div>?

I could use a transparent logo image but like the way it changes color depending on the page. Currently using the fairfield template

Thanks

Phil
