Here is an updated and corrected version of SolarizedDark (again):
This one has white arrows in TreeView controls like the Binder, Outliner and Keyboard Settings.
Do read the Readme.txt file for the place to store the custom icons that come with this Theme.
Use Window > Themes > Import Theme… to place the Theme in the Themes folder and on the Custom Themes menu.
Alternatively, use Window > Themes > Load Theme from file… to place the Theme in the Themes menu until an other Theme is selected.
