Purple cocktails are very "of the moment," but it's not magic -- it's chemistry! Either purple-based liquors, like crème
de violette, give the drinks their stunning hue, or gin infused with butterfly pea blossoms do a quick color change when hit with an acid, like lemon juice, from blue to purple. When swirled with liquids of other color, it gets interesting -- and delicious. These are some of our favorite purple finds to add a little mystery and drama to your drink -- and night.
