MAC Pillars Eyeshadow Quad ($33.00 for 0.19 oz.) is a new, limited edition quad that will be available online on May 26th, and in select stores on June 2nd. The quad contains two permanent shades–Mystery and Carbon–and frankly, Sandstone is so close to Cork (permanent) that it might as well be an all-permanent quad (I imagine most readers will have a beige eyeshadow that would function similarly to Mother’s Milk). The colors work well together, and it creates a smoky, more neutral-toned look, so those who prefer pre-made quads and don’t mind that the pans are glued in might still prefer buying it already put together.

Mother’s Milk is a light beige with neutral-to-cool undertones and a soft, pearly sheen. It had semi-opaque color payoff with a slightly firmer texture, but it seemed to apply and build well on the lid–I didn’t notice the stiffness once I was using it. The color lasted for eight hours on me. bareMinerals Air (PiP, ) is more shimmery, darker (95% similar). ColourPop Supermodel (LE, $6.00) is lighter (95% similar).

Sandstone is a muted, medium brown with neutral-to-warm undertones and a matte finish. The texture was slightly dusty, but it was smooth and finely-milled, which resulted in a very blendable product in practice. It had semi-opaque, buildable coverage that adhered well to bare skin.

Carbon is a medium-dark black with a matte finish. This might be my most-owned eyeshadow ever, which means I’ve seen a lot of variations of it; it varies widely when it comes to quality–sometimes it’s so stiff that even sheer payoff is a challenge, and very occasionally, it’s quite good (I think I recall once or twice!). This time around, it yielded decent pigmentation, though the texture was still on the firmer, stiffer side. When I used it, I found the texture somewhat blendable, but it does take extra effort or building very gradually to minimize how much you have to blend out. Once on, it lasted for eight hours.
