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.
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.
