We’ve had blue eyeshadow on the brain (if not our lids) for a while now, but its appearance in July’s Vogue Turkey, on the lids of Dutch beauty Bette Franke [7], got us thinking about it once again. Makeup artist Hung Vanngo’s subtle use of baby blue shadow to offset Franke's monochrome Vuitton, Dior, and Stella McCartney outfits is so effective, so dreamy, it sort of steals the show.

Which is to say nothing of all of the blue shadows that have been streaming into the office: nearly grisaille shades from Nars; plus indigos both opaque (Maybelline’s Color Tattoo in Brash Blue) and sparkly (Lancôme Show All-In-One Shadow & Liner Palette in Midnight Rush), periwinkles (MAC Satin Eyeshadow in Heroine), pastels (YSL Ombres 5 Lumieres in Riviera), and midnights (Kevyn Aucoin eye pencil in Defining Navy). Whether you're wearing blue as a liner, a full lid, a cat eye, or a graphic quadrilateral, the key to keeping things from veering into Boogie Nights territory is to leave the rest of your face—like Franke’s—fresh and lightly glowing. It's a balance that's easier said than done we realize, but play with it. That's what your Bi-Facil is for, anyway.
