I have never been completely happy with how the widgets of Gtk+ applications looked like. Undoubtedly the “Clearlooks” theme was an impressive improvement, but it has some glitches with some applications (for example Claws-Mail has to be tamed to look good with some themes) and I always had the curiosity of knowing how a theme is made. So I picked up the Chrome theme which uses the Murrine engine, and modified it to have warm gray colors, and the Gnome panel with the same shades as the rest of the widgets. After some tweaking I came up with this:
It makes a smooth, clean environment without too much distractions, apart from the blue shades of the selected items, so it is a good option for everyday use. Especially if you spend loads of hours in front of a computer. It matches nicely with the “Clearlooks” theme included in the latest versions of the OpenBox window manager (which I use).
I think this is nice enough to share, so you may want to get the theme conveniently packaged as a tarball.
