The first picture is a 2020 RT in Sinamon Stick, The second picture is my 2013 Copperhead Pearl RT that I gave my Grand Daughter. I'd have to see them together, but I'm thinking they're pretty close.
The Copperhead was pretty rare with only 347 RT's, and 18 SRT's produced. I don't know the total for 6 cyl. models but I believe it was 381. The SRT's were 2 US, 1 Canada, and 15 Export! I had a 2011 Toxic Orange Challenger RT and a 2008 Dakota in Sunburst Orange. The Copperhead is darker than both the Sunburst and the Toxic.wow i really like that color. I never heard of copperhead pearl though. I wonder how it looks next to toxic orange?
That paint looks real close to my 2006 Daytona Go Man-go paint..just a bit darker.
