Ambiance Blackout Flat is a Modern , Beautiful Fully Dark & flat "reboot" of the Ambiance & Radiance GTK 2/3 Themes. It features a modern and clean "flat" look in your choice of 13 vibrant colors. Ambiance Blackout Flat brings you a fully dark and flat version of Ambiance, However we don't go crazy with making everything "Too Dark" the theme was designed to be a calm beautiful shade of Dark Grey that is still highly visible and not too dark. We spent lots of time crafting and perfecting things so the theme could be highly useable and buttons and all elements highly visible and clear.
