Earth Tones is just what it sounds like- a Gnome shell theme based on soft, mild colors of nature.
Right now it's only a shell theme. A complimentary GTK theme would be nice, but I'm not currently working on it right now. The screenshots show it using the Ronin Adwaita Green GTK theme and the Lin icon set, both available on Gnome-look.
This theme is based on the Hybrid-EDM theme, also available from Gnome-look. Credit goes to those great developers for the nuts and bolts of the theme.
I'm always tweaking colors and visuals, so feel free with suggestions in the comments below.
