roParagraphScreen customization

Hi Guys.,

Just wondering whether its possible to modify the default theme (Gradient blue header and while bg with black text) of Standard templates such as roParagraphScreen? Couldnt find any documentation

1. To add a logo
2. Change the color scheme
3. Modify the font size of a particular word (For ex. in pseduo format: <small>Enter your activation code:</small> <large>ACDEF</large>)

Is it possible, or is it better to go custom screen using 2D graphics??

Thanks,
Sonny
