I have a theme from woothemes and I'm trying to add more stylesheets into the drop down box (Theme Options). It already has 4 (red, blue, brown and green), and I want to add in a few more colors.

I uploaded where they're supposed to go, but it's not appearing in the admin/options panel.

Any ideas where I might need to add the reference to it so that it appears as a choice?
