ColourPop Buttercup is a moderately cool-toned, very light white with a sparkle finish. It is a limited edition eyeshadow that retails for $8.00 and contains 0.23 oz.
ColourPop Buttercup Jelly Much Shadow ($8.00 for 0.23 oz.) seemed to have a translucent base packed with lots of white, pink, and lavender sparkle. The Jelly Much formula is supposed to have "intense" pigmentation, and unfortunately, I didn't see any color description that would mitigate that, so I'm not sure why this ended up being more semi-sheer. I could see this working as a layering shade to add more sparkle over whatever else, and it being lighter and sparkly, that also makes plenty of sense--it's just not how it was marketed.
The texture was watery, cool to the touch, but it applied evenly and spread well on bare skin as a wash of sparkle. The product dried down fairly quickly (without migrating), and it stayed on well for 10 hours without fading or creasing on me.

One of our most innovative formulas yet. Jelly Much delivers extremely high impact looks in a single swipe. Super longwearing, it won’t crease, fade, or transfer; dries down to a powder finish with zero fall out. Here to stay and here to slay! Its unique water-based formula saturates the pigment for immediate intense color right on application. No need to fuss with wetting your makeup brush or using a primer, you’ll get the look of intense shadow right from the pot.
