Not sure if this is the card you mean. But I had a HSBC card that got converted to Cap One recently. Finally got the card. I think it is really smart looking. I would say one of the better plastic cards I have seen. Kind of a dark blueish steel. Has red edge on card which is something I haven't noticed before. You can see it on : http://www.hellocapitalone.com/
Click on the Your New Card for a picture or look at my sig for picture. However, I would say the card looks a better in personal than on the website. In person, the dark blue has more of a shine and texture to it and you can see the red outline on card. I would say it would be my best looking plastic card or 2nd best (after the True Earnings from AMEX which I think looks pretty slick).
