Here's the Marbled Indigo skin I had cut for my PRS-350 to match the blue cover and compliment my Reader's silver edges. You can see by the soft reflection on the back that the skin is matte. I believe Indigo is now a standard order for the 350 and the 950 as well.
People have actually tapped me on the shoulder in restaurants and on public transpo to ask about this particular combination -- mostly because the skin's subtlety and rightness with the cover make people think the Reader looks like that naturally.
