MonoShade

MonoShade is a multi colour scheme premium wordpress theme with advanced features and jQuery effects. It has 4 choices of blog index styles, 5 choices of fonts, 6 extra widgets, 5 animation styles for featured gallery, auto thumbnail generation, 5 ready-made adsense positions and more. All can be controlled via the powerful theme options page.

Also, it can have unlimited colour schemes (it has 8 colour schemes currently). As soon as I make the colour schemes available for download, you can install them easily by copy & paste the files.
