MAC Stony Eyeshadow ($16.00 for 0.05 oz.) is described as a "soft grey concrete [with a Satin finish]." It's a medium-dark, neutral-to-warm-toned pewter with a satin sheen. It's a mix of brown, green, and silver/gray. It had mostly opaque color payoff, and the texture was soft and smooth like the other shades. It lasted for eight hours on me before fading. Stila Substance (P) is darker. NARS Lost Coast #1 (LE, $24.00) is lighter. theBalm #19 (P, $6.50) is lighter, warmer. L'Oreal Gilded Envy (755) (P, $7.99) is darker, more shimmery.
