ColourPop Rex is a slightly cool-toned, very dark blue with a sparkle finish. It is a permanent eyeshadow that retails for $6.00 and contains 0.07 oz.
ColourPop Rex Super Shock Shadow ($5.00 for 0.07 oz.) is described as a "black drenched with multiple shades of blue glitter." It's a medium-dark black with light blue and navy blue micro-glitter. It had so-so color payoff--the black base was noticeably sheer. The upside is the cream-based formula holds the glitter better than a powder would have, but this shade was difficult to work with as it tended to look uneven applied. I had noticeable fall out over time with this shade, though the color didn't crease for ten hours. See comparison swatches / compare dupes side-by-side.

Our famous long-wearing crème powder formula with a unique bouncy-like texture. It's super creamy, insanely pigmented, and has one swipe intensity with zero fallout. For Max Coverage - Use your fingertip and tap shadow directly onto the eyelid. A flat, firm synthetic brush will also work and is perfect for detailed application close to the lash line. To Blend - Use a fluffy synthetic brush with good movement, dip the tip into the shadow and apply with a "windshield wiper" movement throughout the crease of the eye for a soft and diffused look.
