MAC Blue Bang is a slightly cool-toned, medium-dark blue with a pearl finish. It is a limited edition lipstick that retails for $20.00 and contains 0.1 oz.
MAC Blue Bang Lipstick ($17.00 for 0.10 oz.) is a medium blue with cool undertones and a satin sheen. There seemed to be fine pearl, but it wasn't overly shimmery, just a noticeable sheen overall. The consistency was smooth, creamy without being too slick or emollient, and it applied without tugging. It had nearly opaque color coverage that went on evenly, but I did have some color that pulled into lip lines a touch. If you have deeper lines like me, a lip primer might be useful with this particular shade. On me, the color wore well for five and a half hours, left a bluish-purple stain, and was neither drying nor hydrating.
