Monagesque heiress Charlotte Casiraghi was bang on trend when she matched her eye makeup to her cobalt-blue silk Gucci gown this week.

Her inspiration surely came from the fall/winter 2012/13 catwalks where makeup artists used a profusion of azures, Yves Klein blues and ceruleans to create eye-catching looks.

At Anna Sui, makeup artist Pat McGrath traced on a thick line of electric blue on the eyelid, extending it slightly up and past the outer corners and at Stella McCartney she finished off the otherwise pared-back beauty look with a heavy coat of electric-blue mascara.

For Prabal Gurung MAC make-up artist Charlotte Tilbury applied teal hues to models’ lids using diagonal brush strokes to mimic the feather pattern of a bird, while at L’Wren Scott Lancome’s Aaron de Mey created a hazy sapphire eye by smoking navy liner along the upper and lower lashes and blending it up above the crease.

While many may balk at the idea, Tom Pecheux, Creative Make Up Director for Estee Lauder, assures us: “Blue eye shadow is flattering on nearly everyone—every skin tone, eye color, hair shade.”

For a more wearable blue eye M.A.C senior artist Keri Blair recommends using fluffy brush to apply M.A.C’s new Heavenly Creature Mineralize Eye Shadow in Bright Moon.

“Dampen the brush to achieve more opacity,” says Blair, “Or for a powdery, see-through finish, you can apply the product dry.” But the aim is to achieve a “watercolor-like wash” on the lid.

Next, for a dash of blue pigment, “Apply M.A.C’s Heavenly Creature Mineralize Eye Shadow in Sky using a soft angled brush, fashion a ‘v’ shape in the outer corner,” says Blair. “This adds dimension and gives a playful quality without being too graphic.”

Finally, to add more depth and definition along the upper lashes, use a black gel liner. Blair recommends M.A.C Fluidline in Blacktrack using a stiff angled brush.

“Follow the natural shape of your eye, keeping the line clean and precise but without a wing. A cat-eye is beautiful, but pairing it with teal shadow can make it look 1950s-esque and dated.”
