This eyeshadow single is named Fireball and rightly so. It’s described as a peachy color with a pink shift, meaning the color will change in different light. This baby pink shift shade goes for $10 only today.

Spiked is an ideal color to blend into the crease of your eye. Described as an orange matte, it’s one of the few non shimmery shades of eyeshadow singles offered on Ulta’s site. This color could be a looker. Plus, it’s $10 today.

Fans can grab Urban Decay's Moondust eyeshadows that have a cream to powder formula. This one in the shade Solstice is a highly pigmented grey shimmer that's best applied with a wet finger for extra shimmer.

Half Baked has a whole lot of wow factor with its gold specks. The shade is described as a golden bronze shimmer. For a night out or a bold day look, it’s a shade that stands any time of day.

Despite its name, Mildew is a cool tone green shimmer. Its mossy green appearance comes with a golf shift, so the shade is like a two-for-one glow up.

Relish is a warm wine-colored matte shade and its wearable either during the day or at night. Thankfully, this one is $10 today.

This Moondust shadow in the shade Extragalactic is fitting due to the high-pigmented red that comes out of it. Although it looks pink, Extragalactic is actually black with red sparkle.

Lounge in the pan looks straight up green, but is described as red with a green shift, meaning the red shimmer will shift to a deep green shimmer when the light shifts.

There's no doubt there's going to be a color beauty fans will love in this selection. Plus, it's hard not to like makeup a little more when it's discounted for half the price.
