"Somebody sent me a bunch of colors and they were so pretty. All of them were great and kind of monochromatic, so I was like, I need to try this," she tells me.

While Goldstein often likes to stick to the same shade family, she also says there are no rules for nailing the look. "It doesn't necessarily have to be just like light to dark. I always like to do like one pop of like a random color. So, I did green ones and then a yellow," she said. "It's in the similar wheelhouse, but just a little bit off. So, it adds that extra umpfh to it."
