Since this makeup look is all about the eyes, the rest of the routine can be kept pretty basic. Light foundation and blush allow the eyes to really pop -- not that the colors exactly need the help.

Step 1: Conceal any imperfections with a light wash of foundation -- we tried out IT Cosmetics IT-O2 Ultra Repair Liquid Oxygen Foundation, $38 -- applied with a sponge for a sheer look. We've recently fallen in love with EcoTools Foam Applicator, $5.99. Cover under-eye circles with a brightening concealer.

Step 2: Using an angled brush, create a cat eye using a vivid yellow cream shadow, like Make Up Forever's Aqua Cream in shade 24, $23, starting from the inner corner of your eye and flicking the brush upwards at the outer corner. (For a step-by-step tutorial on the perfect cat eye, see this video: Erica's 60-Second Cat Eye for Beginners.)Extend a little further than you normally would for added drama. Add more cream shadow to your brush and, using the line you already made as a guide, make the cat eye thicker. Repeat until you hit the desired thickness.

Step 3: Wipe off your angled brush, then use it to apply a thick line of blue cream shadow, like Make Up Forever's Aqua Cream in shade 24, $23, below the lower lashes. Make sure to start from the inner corner of the eye and extend upwards so that it meets the yellow liner.

Step 4: Apply a peachy blush to the apples of the cheeks. Then top off your lips with a neutral gloss and set the look with powder. Ta-da!

The glittery eye shadow, braided hair, and bronze smoky eyes we recreated earlier in the week seem like child's play compared to this look from the Chromat "Mathlete" presentation. Trust me, we could have really used a mathlete -- or at the very least a ruler -- to help us with this angular look. Instead we settled for some scotch tape and a really steady hand. Oh, and lots of Make Up Forever Pure Pigment, $20, in white.

Now, we're not saying you could pull this off in the office or your next backyard barbecue, but we loved the edginess of it. For our challenge, we skipped the alien eyebrows, slicked back her hair and came up with a Chroma-inspired look that would be fun for a fashion-forward costume party (Halloween is just around the corner!) or rave-y music festival.

Props to our intern/model, Hayley, who wore the look for the rest of the day -- granted, she didn't set foot outside of the office until it was time to go home (and she told us people in traffic next to her openly gawked). Click to see our take on the Chromat look.

Step 1: First even out your skin by applying a multi-tasking product (we like MAC's Prep and Prime BB Beauty Balm, $30) with a foundation brush.

Step 2: Apply a small piece of scotch tape just outside the outer corner of your eye, with the bottom corner of the tape lined up to the top lash line. Apply a second piece of tape along your cheekbone, starting at the middle of eye, to meet the corner of the first piece of tape. (Essentially, you're creating a reverse point with the ends of the tape.) Fill in the space between the pieces of tape with a neutral eye primer to keep the makeup in place.
