Gucci Cosmic Deco Magnetic Color Shadow Quad ($65.00 for 0.17 oz.) is set of smokier shades that leans warm in tone. Three of the four shades are quite shimmery, and those three performed better than the one more matte shade, unfortunately. I’m always surprised to see brands miss on a matte black eyeshadow, which should be a very basic color and one where blendability is really necessary for it to perform well and be as versatile as a basic should be.

Cosmic Deco #1 is a brightened, white gold with a metallic sheen. It had good pigmentation with a smooth, dense, and buttery consistency that applied well to bare skin and lasted for eight hours on me.

Cosmic Deco #2 is a medium-dark, olive green with warm, brown undertones and a frosted finish. The texture was soft but dry to the touch, where the shimmer felt loose against the eyeshadow itself, so I found it more challenging to apply. It’s one that would work better with a damp brush or over a primer, I think, to minimize the fall out and tendency to sheer out. It lasted for eight hours on me.

Cosmic Deco #4 is a medium-dark black with warm, brown undertones and a smattering of silver shimmer over a mostly matte finish.
