Hi,
to begin with I want to note that I am not a developer and nowhere near having any clue of how this wonderful module (or anything else in Drupal, for that matter) works "under the hood".

But as it is now possible for users to individually change which color scheme should be displayed, I can only assume (please feel free to delete this issue, if I am mistaken here) that it is possible to include the feature to change the color scheme that is displayed by the path of the node that is displayed (or by any other information about that node). This, I think, would only be possible, if the users did not have the possibility to change the color scheme on their own; at least a conflict must be avoided here.

For better understanding let me give you a simple example:
I am the designer of a site that has following structure:

example.com
example.com/forums
example.com/forums/1
example.com/forums/2
example.com/forums/2/1
example.com/blogs
example.com/blogs/1
example.com/blogs/2
example.com/blogs/2/1

And I want to make e.g. the homepage appear in a blue color scheme, the forums and all subpaths red and the blogs yellow.
