WordPress Theme Demo – Allow CSS Selection

Hi,

I am looking for a plugin that will allow my website visitors to select various WordPress themes for demo purposes that not only allow the theme to be previewed but will also allow for the selection of color schemes.

I have found some good plugins to simply preview themes – but I have not found a plugin that will allow for selecting theme color schemes (if the particular theme has more than one color scheme to select from as an option).

Your input would be appreciated. Thank you!
