MAC Concrete is a neutral-toned, medium-dark taupe with a matte finish. It is a permanent eyeshadow that retails for $17.00 and contains 0.05 oz.
Concrete is described as a "muted taupe brown [with a Satin finish]." It's a medium-dark, muted brown with a gray-ish overcast but still has some warmer, brown undertones. The texture was soft, smooth, and it had good pigmentation. This shade wore well for eight hours on me. Kat Von D Shadow Box (P) is warmer. Tarina Tarantino Delightful #5 (P) is similar. Chanel Charming #4 (LE) is warmer. Too Faced Dark Chocolate (LE, $16.00) is darker. Urban Decay Secret Service (P, $18.00) is lighter, warmer. NARS Bali (P, $24.00) is more matte. MAC Cross-Cultural (LE, $15.00) is warmer. MAC Charcoal Brown (P, $15.00) is similar. Benefit Quick, Look Busy (P, $20.00) is similar. See comparison swatches / view dupes.
