MAC Pale Pipa Eyeshadow ($17.00 for 0.05 oz.) is described as a "pastel turquoise [with a Matte finish]." It's a muted, medium aqua with cool undertones and a matte finish. This was the worst performer of the four, as it was semi-sheer in coverage, hard to build up, and moderately powdery--so it was already sheer to begin with and tended to sheer out further applied. I would recommend using a white, tacky base underneath this one to give it something to adhere to. It lasted for seven hours before fading.
