It's time to get groovy, baby. Just as mood rings of the '70s supposedly changed color to match the state of one's emotions, mood-changing makeup works quite the same way. Although, in actuality, it's your body heat and chemistry that are producing the color alterations. (Bummer. I kind of loved the kitschy idea that these products actually center around your inner disposition.) From nail polishes to crazy-hued lipsticks to glosses, here are a few colorful finds to put you in a good mood.
