Yellow
Egg-yolk colored nails are colorful and playful; try
Thakoon for NARS polish in Amchoor ($18;
narscosmetics.com). The more daring can try yellow eyeshadow, such as
MAC Electric Cool Eye Shadow in Brilliantly Lit ($18.50;
maccosmetics.com) — just pair it with a thin swipe of black liquid liner to keep the look sophisticated.
