When I wrote the article on “color chameleons” about a year ago, I especially loved the idea of nails that change color on their own. So I love that LeChat has launched a color-changing gel-polish, dubbed “Mood.” Available in six colors (well, 12, if you count the colors each one transforms into!), it’s a fun and flirty gel-polish that stands out from the pack. Shown is Groovy Heat Wave — and that’s not a reverse moon manicure, that was caused by LeChat founder Newton Lu touching  a portion of the nail to make it change colors.
