Buff is a light, peachy beige with warm undertones and a matte finish. It looked yellower applied than it did in the pan, where it looked like a true peach (so some orange). The texture was somewhat powdery, thinner, and had some fallout during application. It had mostly opaque coverage that lasted decently for seven hours before fading noticeably.
