Hi Charlie,
I just replied to your PM
Ferrari usually allows the customers to order any car is any color, current, past or custom. They also have an extensive range of blues. That sometimes makes difficult to identify the colors. From the picture, it looks like Ferrari Azzurro Met code 515C. This color was available in the early 90's and probably before that as well. There are other similar colors but I think California Azzurro is more silverish, and NART blue is darker, and Tour de France blue is also darker.
Azzurro Hyperion 517 could be another possibility, but I'm more inclined to the Ferrari Azzurro met.
I hope this helps. Anyway, Ferraris always look good in any shade of blue
Thanks,
