Razer makes a lot of nice-looking and high-performance (if you could call them that) peripherals, like keyboards, mice, and headsets. If you browse their catalog, I'm sure you'll find something you like. Logitech has a more diverse array of products, including non-gaming ones.
I suddenly remembered the Saitek Cyborg keyboard, which has multi-colored backlighting. Different parts of the keyboard (especially the WASD cluster) can be lit up with different colors. If you can borrow them from a friend or use them somewhere, I suggest you do so that you experience using it and find out if you really like it.
