ColourPop Moondancer Ultra Matte Liquid Lipstick ($6.00 for 0.11 oz.) is a deep plum with subtle, cool undertones and a matte finish. It had good color payoff in a single layer, though it was not opaque. The consistency was fluid, almost too runny, and smooth, which made it comfortable to apply and easy to spread out (that's where it seemed to be almost too runny--it was too spreadable!). There was a bit of color that dried down in my lip lines. On me, the color was still going strong after six hours of wear but had started to feel a bit drying after four horus of wear.
