Is it green, or is it yellow? Either way, anything with even just hints of citron has been grabbing my eye lately. I say either go LOUD with something big, like a full citron gown or statement necklace. Or you can keep it simple with the slightest color pop to grab the eye. If you're looking for an easy way to incorporate a citron piece into a room or outfit, pair it something a dark (but not black), like charcoal gray. I think this makes for the perfect neon-neutral combination.
