I got a refill pan as I have a few spot to fill in my Mac palette.
Copperplate is a muted taupe colore with a Matte2 finish. It's cool toned and leans towards the grey part of the color spectrum.

The color is kind of powdery and stiff in the pan and needs a little bit of work on the lid. It blends easily but be careful since it sheers out with each swipe of the brush. I do suggest you pat it on and not swipe it to help the color stay in place.
I cannot say much about its longevity, but I suspect is going to be quite similar to the other matte eyeshadows I own: lasts about 4 hour with no primer, the whole day with a primer.
While I like the shade and the full matte finish, I am definitely a bit disappointed in the pigmentation and the application Copperplate offers.
