Blu Theme is a neat and simple theme for your S60 phone based around the color blue.
It features an ocean blue background wallpaper and applies a blue, black and white color scheme to your system's context menus.
The new S60 icons in the Blu Theme look great. Again, they are simplistic in their design and are very brightly colored, making for an eye-catching look.
The desktop background could be perceived as boring by some, but if you're looking for an elegant theme and your favorite color is blue, then Blu Theme is for you.
