Ok...... I'm lost.

What I have now is 4 basic styles.. Based off the same Default template. The styles are only color changes for the most part. This is to give my users some "toys" while I play..

What I want. Is another template "style" that will be the one that I import changes to from a testing board as I see that they are going to work fine. I will be changing the base template and the layout. When complete it will become the "final" and will be used by all visitors. In the mean time I need to keep the styles above available until I'm ready to go live with my final.

This new template / style sheet needs to be started from what I've built so far and as I change it online it cannot change the 4 basic styles built on the default. How do I do it?
