The orange is NOT close to a "real" tortoise frame! "Real tortoise" as in commonwealth frame colors. All of them are the same neon acid colors just with an added tortoise effect. I thought I'd get the orange because they looked the closest in stock photos but after seeing a picture of the real thing it's off my list...I can post the pic if needed.
Clearer pics of the Orange Tortoise are up on eBay, there's a few out there for sale already. Pics of the Blue Tortoise have been posted on this board. They look more Crystal Blue than Acid Blue, maybe due to the black tortoise effect added. Pics of the others can be found in the 2012 Oakley thread, but they're not too clear.
As KyleTheSid said, these are just the Acids with a black tortoise effect added. They also come with the same design Oakley microbag as the Acids but it too has had a tortoise effect added which is a nice touch but in reality all these is Acids with a paint effect. They now come with coloured lenses other than grey but, as mentioned in the OCP thread, these lenses can be bought separately soon anyway. Not too fussed about getting these, maybe when they get discounted I might.
