MAC Pigment is AMAZING! I have nothing bad to say about it, but took off a half a star because I found this pigment faded slightly. JUST SLIGHTLY. Other than that, I am hopelessly in love with this pigment, as it is the most amazing bright magenta you will ever find. NOTE: I purchased this in a PRO store.
Magenta Madness is a neon fuchsia pink. It reads more fuchsia than magenta to me, though I wouldn’t debate you on that ’til the death. This shade is not to be used in the eye area per MAC’s safety insert. Inglot #362 is pinker, while Make Up For Ever #75 is closer but darker. MAC’s Neon pigments take a fair amount of work, and I can see why they’re a pro product. It’s better mixed with other base products (e.g. creams, mixing mediums, etc.) than applied straight to the skin. It has a matte finish, so it ends up looking chalky just swatched dry. The texture is silky soft–very finely milled–but it means it can look patchy when applied damp.
