I never liked Ubuntu's Humanity theme, New Wave theme in 9.10 crashes some applications, like F-Spot, and both are brown. Now Lucid is about to make purple (sic!) it's default colour, so that's not for me as well.
When I used to work with Windows XP, I used a theme named NeogenX1, from a deviantart publisher, dobee2, and I simply loved it. So I wanted to find something similar to that for Ubuntu.
I've searched through deviantart's customisation part3 for this, and I've found nothing. Fortunately, I came across with Ubuntu Tweak4, some kind of system management software for Ubuntu. It has a third party repository list from ppa, and there was a theme repository, named gnome-colors5. Inside of it, there's a pack, shiki-colors6.
This is exactly what I was looking for.
