Make Multiple colors for Templates?
 

Well I was wondering if anyone knew how to do this.

I currently have a template with 3 options a liquid, fixed, and fixed with a background (they all have minor coding changes). I also have multiple colors for the template. Currently they all show up as different templates, but I wanted to make it so:
There are 3 options for the templates in the template selector: template with a liquid, fixed, and fixed with a background
Then I wanted to either have a bar or little images with colors in them, and when you click on one of those, it changes the color.

I was thinking I could just do an If statement, I dont know what if statement it would be anyways. But either way the place where you enter the directories in the "style options" for a template doesnt allow If statements, im pretty sure.

Any ideas how to do this?
Thanks.

EDIT- wow, the similar threads showed up, & that might be it. Ill try that first
