Alternative Default Templates?

[Zilvia]

Forgive me for the basic question, but I have searched and cant seem to pinpoint these type of styles.

I am looking for default styles but with variant colors. Most of the mods I see are usually doing other modification to images or other parts of the design, I just want a XML to import that will change the default color options. Do these exist and if so how do I go about finding them? Thanks!!!
