MAC Which Witch is a very warm-toned, very dark purple with a natural finish. It is a limited edition lipstick that retails for $19.00 and contains 0.1 oz.
MAC Which Witch Lipstick ($17.00 for 0.10 oz.) is described as a "deep plum [with an Amplified finish]." It's a blackened purple with subtle, warm plummy undertones and a dash of violet micro-shimmer. It had semi-opaque pigmentation with a consistency that had moderate slip--it definitely slides around on me and could be a shade that feathers for some as a result. Application could have been better, but it isn't the worst I've seen; some visible streaky and general unevenness, so I would recommend a lip liner with this one. It wore well for four hours and left a stain behind, while the formula was neither hydrating nor drying. MAC Power My Spirit (LE, $19.00) is cooler (95% similar).
