I thought they were meant to be beige too at first... then I saw some better condition looking ones online. I just finished replacing the tact switches on mine and had to remove the buttons in the process - you can really notice the difference on the underside where they haven't been exposed to UV.
Here's a shot of two of the program buttons, the one on the right shows the original color,

Has anyone had experience with Retr0bright (http://retr0bright.wikispaces.com/) to turn them back to their original colour? Or any other methods?
