Somebody mentioned Panther Pink already, but how about some of the other wild and crazy colors from the 60s? Tor-Red. Sub-Lime. In-Violet. Come-and-get-me Copper. Hemi Orange.
The 450 model came in a black called "Scratch Black" that has random silver streaks through it. Really sharp! There was also a medium blue called "Numeric Blue" that had multi colors and was gorgeous! It looks like a bright blue lagoon. Yum!
Since the the smarts body panels are so easy to remove and paint I'm sure we'll see some wild colors, and I'll be diggin' them all!
P.S. Don't forget there are vinyl stick ons large and small out there. Shades of old VW vans!
