That blue Pozzi looks a lot more blue than the 550 one.
I think it's all down to people using automatic cameras, Barry. Or not knowing how to use a manual camera correctly. Things like lighting (fluorescent light compared to halogen or daylight) also make a huge difference as they can give a colour cast, darken or brighten the car etc...
For instance, in the first interior shot of the 550 I would have sworn the carpets are black. Then on the photo of the shelf, you can clearly see it's blue.
Pozzi is a notoriously difficult colour to capture. The best representation on these photo's, IMHO, is just above the reflector on the rear arch of the F430 on the photo of the passenger side rear wheel. I have hardly seen that colour on any of the other photo's.
