The guys behind the RAVEfinity project have released an updated Humanity Colors icon theme for Ubuntu 14.04 (and older), which work great with Ambiance and Radiance Colors GTK themes.

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.
