Matte is a finish, not a single color. A microscopically textured surface scatters light instead of returning a sharp reflection, so almost any hue can appear matte.
This restrained set uses Ash Gray, Rosy Brown, Dark Khaki, Dark Sea Green, Light Slate Gray, and Sienna to suggest that low-sheen character.
The HEX values describe the colors themselves, not the gloss of a real material.
