Audrey's 1965 Barracuda project

My wife want this exact color on her Barracuda. Anyone knows if this is an original color or not? And if so which one? To me, it looks like a silver metallic with a little bit of champange tint to it. Can't really match it with one of the original colors that I can find on the web.
Photo is taken by a friend of my wife, it was for sale in L.A recently. (And her friend also talked to the owner, he didn't know either). It does look good with the red interior.
