The thing is - Fire Black is NEVER going to represent in any photo taken from more than a few feet away. It's just too subtle. A pic taken close up MIGHT show up, but you'd have to carefully catch a sunlight glint line. Sitting in the sun, you see [basically] a black car as you walk up... ...but when you get about 6' away you start to see the real character show through. Fire Black is a great way to have subltety and drama in the same car.
It as quite a bit of depth, with bronze, gold and red metalflake. In anything but sunlight (or, say, under showroom lights), it's a black car (at night, on overcast days, etc.). But then the sun hits it and the amazing character shows.
As previously said, with a black/tan interior it is very very rich. I also think that McLaren Orange calipers behind stealth-finish wheels would accentuate the metalflake quite well.
In the end - until you see a car in person (or hold a sample in your hand) - you're unlikely to be able to tell what's going on with Fire Black.
