Part of the reason the palette worked so well is that makeup artist Jenn Streicher kept Emily's eyes and cheeks simply elegant, opting for a clean-skin palette to begin with, starting with Hourglass No. 28 Primer Serum as a base, followed by Dolce & Gabbana Perfect Finish Foundation. But another reason the palette worked so well is all thanks to the science of color. Pink (as seen on Emily's lips) when paired with green (as seen on her earrings and in her frock) is a winning combination. The reason is because pinkish tones are directly opposite of greenish tones on the color wheel, so Emily's overall ensemble made for one truly spellbinding style.
