As stated in previous posts, LXAppearance is currently being rewritten. Today, the rewrite is finished.
Now LXAppearance becomes the most feature-rich Gnome-free gtk+ theme changer.
Let’s see a screenshot:
If the gtk+ theme you use supports color schemes, such as Clearlooks, you can customize these colors in LXAppearance, just like what you can do in gnome-appearance-properties.

Later, LXAppearance2  will replace LXAppearance and move to lxappearance git repository.

Main features of LXApppearance2:

1. Depends on gtk+ only. Can work completely without gnome.
2. Friendly and Gnome HIG compliant user interface
3. Provides real-time preview of the selected themes
4. Changes icon theme
5. Changes cursor theme in a almost desktop independent way.
6. Supports color schemes. You can change the color used by themes if the themes support gtk color scheme.
7. Able to install/remove icon and cursor themes in a user-friendly way
8. Provides additional options for gtk toolbars
9. Able to turn off event sound provided by libcanberra-gtk-module.
10. Changes default font used by gtk+ applications
11. Although this is a LXDE component, it works perfectly well outside LXDE and it has no LXDE dependencies.
