Bobbi Brown Slate Eyeshadow ($21.00 for 0.08 oz.) is described as a “medium grey.” It’s a softened gray-tinged taupe brown with a matte finish. MAC Omega is lighter, warmer. theBalm Celebrational is darker and has a satiny sheen. Bare Escentuals Vow is a few shades darekr and has a strong red undertone. MAC Twilight Falls is frosted and darker. MAC EarthlyM is a little browner and has a shimmery finish. Inglot #360 is a bit darker and less gray, but it was the closest I could think of.
