NYX describe this as a dark pink brown shade, I would say it is a pinky nude rather than a brown.
It also also described as being pigment rich colour that stays in place with a silky matte finish that never feels dry. I agree with that, I think it is pigmented and does last many hours on the lips. As for it being matte I would say it is more of a creamy, semi matte, rather than it being a full on drying matte.
On my hand it swatched more nude;
On my lips however it leaned slightly more pink toned;
