The answers in this thread raise all kinds of interesting thoughts with epubs that I hadn't ever thought of. Considering that the screenshots from the screenshot hack are in full colour I guess it makes sense that font/page colour could be specified and would be rendered as such except that it would display as grey scales. I've never really delved into CSS or any of that so I guess since I just assumed it was black and white by default and never thought of options. Learning lots!
