the two diffeent 5s and the 500, Contrary to my previous statment, it turns out the 500 is diffeent from the 5. The scanner really shows the difference. They look much closer with the naked eye. The 5 has more of a pale greenish look while the 500 has a tad more creamish pale yellow. Agaion, by the eye...the 5 goes not look quite as green as it does with them all together.
