Gang, I have just uploaded an update to the entire LX-Colors GTK2/GTK3/Openbox themes suite to my Google Drive account as well as to Box-Look.org. This update is now compatible with GTK 3.20 plus adds the following features:

• 2 new colors: Carbonite (dark gray) and Tribute (light gray, kinda gold-ish)
• A new update to the Arc-Colors wallpapers and the GNOME-Colors icon theme series (included), courtesy of Kylie McClain of Somasis.com. Please be sure to show her some love and thank her for her hard work, y'all.
• Mobile-Colors wallpapers, which are basically the Arc-Colors wallpapers re-sized for use as smartphone wallpapers, in order to allow you to use the wallpapers while on-the-go away from your desktop or laptop.

Here's a little demo of what it looks like: http://imgur.com/nWqPjUc
