Blue-green nails and lids have been big for a few seasons, and, from what I’ve seen for spring, beauty is going even greener. (From top left) Givenchy Color Kajal in Vert Invention is a muted lime with a tiny hint of blue; Clarins Crayon Khôl in Intense Green is deep pine with just a bit of navy. Both are a lovely, not too “look at me” alternative to basic black liner. I’m generally not a fan of matchy-matchy, but in this case I’m all for echoing the same tone on nails. My pick: Jin Soon Nail Lacquer in Tila, a brilliant blend of forest and turquoise.
