Need a Ubuntu(ish) theme

I’m setting up a Ubuntu community site using WordPress, for the final “touch” i need a Ubuntu theme or something along those lines (Anything somehow related to the color brown)

For a clue, have a look at https://www.ubuntu.com/

So far I’ve come across two themes made with Ubuntu as an inspiration:
https://www.ubuntued.com/?p=5
https://wiki.ubuntu.com/Udienz/WordpressUbuntuTheme

None of these themes looks good imho, so I’d like to hear if anyone know of other themes that might suit my need.

Ps.: I’m capable of doing minor graphical changes, so if anyone finds the perfect theme for me, but ex. with the wrong fading background color etc., please let me know anyway.
