This is a really simple and stupid gtk theme made with just 3 colors.
Includes a little bash script for changing them like this:
$ sh p3c_themeator.sh #0000ff #00ff00 #ff0000
Playing with Agave, you can obtain beautifull colorsets.
It was made for adapting gtk apps to my Fvwm theme, so when I changed Fvwm's appearance I could change Gtk's accordingly too with just a call to it's script.
The script assumes the theme to be in ~/.themes/ and uses gtk-theme-swith(2) for changing it, but can be easily modified.
