A while back we've posted an article about Ambiance & Radiance Colors, a theme pack that provides Ambiance and Radiance available in 8 different colors. Well, since then matching GNOME Shell themes were added and the GTK themes got some fixes from Light Themes Evolved, like a dark sidebar for Nautilus or unified menu and titlebar.
The themes are beautiful, but a theme pack is not really complete unless you have a matching icon theme, so Jared, the Ambiance & Radiance Colors Theme Pack author, has released a recolord Humanity Icon theme called "Humanity Icons Colors", which comes in 8 colors, with support for both dark and light panels: blue, graphite, green, orange, pink, red, yellow and purple.
And of course, the new icons look great with Ambiance & Radiance Colors. Here are a few screenshots:
Update: Ubuntu users can install Humanity Icon Colors theme using the RAVEfinity PPA (which also provides Ambiance & Radiance Colors):

Thanks to Jared for the tip!
