Illamasqua Sadist is a very cool-toned, dark blue with a matte finish. It is a permanent eyeshadow.
Illamasqua Sadist Eyeshadow ($20.00 for 0.07 oz.) is described as a "matte bright royal blue." It's a rich, deep, medium-dark blue--there's a little indigo/purple that tints it so it looks very cool-toned. It had a matte finish, and the color payoff was quite good. The texture was soft, finely-milled but not powdery--yet still blendable and had a lot of pigmentation. It lasted for nine hours without creasing or fading, but there was some residual staining after I removed it. Sephora My Boyfriend's Jeans is shimmery and darker. Sugarpill Velocity is similar but slightly lighter. Urban Decay Chaos is similar in color but has some shimmer. NARS Rated R #2 is much lighter. NARS Outremer is darker. Sugarpill Royal Sugar is a touch brighter and shimmery. Inglot #388 is darker, less blue. See comparison swatches.
