It's not a tan like Gobi Beige, it's FT6 Burnt Tan Metallic, a dark metallic brownish, beigish, taupish, khaki-ish, fleshtone color. There was a 69 hemi Daytona in Otis Chandler's old collection that was that color.
Another bizarro coincidence is that the 4 speed "tan" Charger was owned by the guy I bought the 71 yellow hemicuda ragtop from. In 1986, he sold that car to Dave Jones in Indiana and it was featured on one of those famous musclecar posters from back in the 1980's. It was a beatiful car with power windows and a white vinyl top if I recall correctly.
It would be #8 on the chart below:
