As i said, the darkness of some elements is the only thing that may cause your eyes to glitter after a while, but this is also exactly the source from where the elegance of this theme stems.
The contrasted white colored info bubbles, the mildly transparent dark panel and light grey selection bars improve greatly the everyday usage situation experience.
A very nice theme in general, that works well, looks nice and fits my taste of elegance. I plan to keep using this one for some time :)
It is suggested that you combine this theme with the Lato font family that will provide a more stylish result using open source content.
