Recently, I have been using what will become Fedora 21 as my day-to-day machine, (side note: I have found it to be pretty stable for pre-release software). One really nice improvement that i am enjoying on Fedora 21 is the addition of the solarized color scheme in both the default terminal (gnome-terminal), and the default graphical text editior (gedit). Solarized comes in both light and dark variants, and really makes these applications look fantastic and works really well on a wide range of displays and screen brightness levels.
