MAC Atomized Retro Matte Liquid Lipcolour Metallic ($21.00 for 0.17 oz.) is a medium-dark purple with subtle, warm undertones and a metallic sheen. It had semi-opaque pigmentation that applied fairly evenly, but the the consistency was on the thinner side and needed some care to ensure an even, smooth application. I would recommend waiting for it to dry and then applying a second layer if full coverage is desired. The formula itself dried down quickly but did not feel clingy or dry on, and the thinner texture kept the color from flaking off as it wore away. On me, it lasted for seven hours and was only slightly drying after five hours of wear.
