This 356 was at the Atlanta Porsche Experience Center cars and coffee event this morning. Not the same one I saw in Hilton Head but I think it's the same color. I talked to the owner of this 356 this morning and confirmed the paint code as Bali Blue.

Edit: I've uploaded the picture 3 different times and the uploaded file link is broken every time. Looks like maybe the forum server has a little glitch. I'll check back later to see if the link works.
