Well since you asked, I think the GT3, blood orange, pumpkin shade is a bit on the trendy side. And a trend which is about two years old. Just yesterday I saw an S4 in this shade. It looked cool but soon this hue will appear on every Nissan Sentra and Honda Civic you run into.
Tangerine is a classic 911 color and I doubt there are a lot of cars which can pull it off quite as nicely.
