ColourPop Hippo Super Shock Cheek ($8.00 for 0.15 oz.) is described as a “cool-toned icy lavender.” It’s a cool-toned, pinkish-white with a pearly, violet sheen. It had mostly opaque coverage when applied with a fingertip, but the consistency was creamy and smooth, so it was easily blended down to sheer coverage, or you can apply with a brush to achieve less payoff initially. Very fair skin tones could easily wear this alone, but it’ll pop more on darker skin tones when paired with a blush (it looks amazing with Sticky Sweet). On me, this shade lasted for seven and a half hours before fading slightly, which does make it one of the shorter-wearing shades I’ve tried so far. ColourPop Monster (P, $8.00) is less cool-toned, pinker-based, though on my skin tone they appear more similar than not until I turn my cheek, then you get a stronger duochrome sheen out of Monster that’s a smoother, less frosted sheen. Makeup Geek First Love (P, $9.99) is darker, less shimmery. NARS New Order (P, $29.00) is darker. MAC Unconventional (LE, $21.00) is cooler-toned, darker, less shimmery. MAC Full of Joy (P, $21.00) is darker, cooler-toned, less shimmery. MAC Pearl Blossom (LE, $26.00) is warmer, slightly darker. See comparison swatches / compare dupes side-by-side.

ColourPop Monster Super Shock Cheek ($8.00 for 0.15 oz.) is described as a “light pink with highly opalescent duo chrome finish.” It’s a very subtle, pink-tinted white with pink to violet pearly sheen. The duochrome effect is visible, but of course, at angles, so it’s a chameleon of a shade that very much shifts as you move your face or different light sources enter the equation. It’s one of the more complex and interesting highlighters I’ve tried. Like Hippo, it becomes even more interesting when layered with blush, as it can change the way those appear in undertone. On me, this shade lasted for eight hours. ColourPop Hippo (P, $8.00) is cooler-toned, more shimmery. Giorgio Armani No. 08 (P, $59.00) is darker, pinker. MAC Pink Buttercream (LE, $30.00) is darker. MAC Pearl Blossom (LE, $26.00) is warmer. See comparison swatches / compare dupes side-by-side.
