Update 17 September 2017: the latest version is out with preliminary support of GNOME 3.26

Flat-Plat-Blue Theme

Flat-Plat-Blue Theme is a GNOME Shell/GTK Theme forked from Flat-Plat Theme with the following refinements:

  • All coloured elements (e.g. check boxes, sliders, switches, etc) are changed into blue to provide a more consistent and comfortable visual experience;
  • The top bar is transparent when no window is maximised (starting from GNOME Shell 3.26);
  • Open Sans is the default font of the theme; and
  • Other minor changes and fixes.

The latest version features the redesign of running-app indicators for dash and dash-to-dock (See Screenshot).

The theme includes three variants:

  • Dark title bar and light window’s background (Flat-Plat-Blue)
  • Light title bar and light window’s background (Flat-Plat-Blue-Light)
  • Dark title bar and dark window’s background (Flat-Plat-Blue-Dark)

Each variant comes with normal and compact themes for different screen sizes.

The Origin Story

I forked and modified the Flat-Plat Theme for personal use, but I reckoned there were people out there who wanted a colour scheme that was more comfortable to look at, so I put together the theme and release it. You are welcomed to fork it and make further modifications yourself.

  • The gnome-themes-standard package for GTK2
  • The pixmap (or pixbuf) engine for GTK2
