The "Olso blue" photo
Some more of the same press shots, see how it looks more like Cobalt blue.

That's really interesting because then that would mean Olso blue existed for a while. These are the original press shots released back when the 997TT was first announced. I'm still pretty sure that it's Cobalt blue and that Porsche may have accidentally mislabeled it Olso blue in recent times.
