MAC Umbrella Sky is a slightly cool-toned, light blue with a satin finish. It is a limited edition lipstick that retails for $20.00 and contains 0.1 oz.
Umbrella Sky is described as a "bright sky blue [with an Amplified finish]." It's a soft, aqua blue with cool undertones and a satin finish. It had semi-opaque pigmentation with a noticeable sheerness to it that really made it look streaky. It also pulled into lip lines due to the more emollient and thicker consistency of the formula. It lasted for three hours on me with significant settling into lip lines. It was a little drying, too. Get comparison swatches / compare dupes side-by-side.
