Theme Configuration

Hi,

I'm trying to add a theme option that allows a user to input hex color codes for a few different areas (text and background colors, etc) and upload a logo. I looked at the documentation and at the Rhythm theme (config.ini, header.php and custom.php). I think I get how the the theme switching works, but I'm not finding anything that translates to quite what I need. Any chance the documentation for the get_theme_option() helper could be expanded to include some additional options and examples?

Thanks,

Erin
