Relaxing color, enough texture to keep it from being boring without being at all distracting. The tabs, labels, and icons are crisp and easily readable, and the live tab is readily distinguishable. All pluses in my book. I am at my computer a lot, do not care for minimalist look, and have a lot of tabs open at a time, working from one to another. This is the kind of design that is made for people like me.
