L'Oreal With a Twist is a moderately warm-toned, medium-dark lavender with a metallic finish. It is a limited edition eyeshadow that retails for $7.99 and contains 0.12 oz.
L'Oreal With a Twist Infallible 24HR Eyeshadow ($8.99 for 0.12 oz.) is a pink-toned lavender with a frosted, metallic finish. Applied dry, it had semi-opaque color payoff; enough punch to be noticeable but not as intense and rich-looking as when applied damp. It was a little clumpy, though, when dampened, so press firmly against the lid to minimize this transferring onto the lids. Make Up For Ever #54 is purpler, less pink (and a cream product). Guerlain Attrape-Coeur #4 is lighter. Urban Decay Grifter is slightly pinker. NARS Marie-Galante #1 is similar in color but is sheerer so it's not quite a dupe. Benefit Fancy Pansy is cooler-toned.
