Actress Juliette Lewis was eye-catching to say the least as she rocked a cool blue 'do on the red carpet at The Switch premiere on Monday.

Never one to follow fashion convention, Lewis said the secret behind her sapphire locks was her musical alter-ego. "I have a whole other rock 'n' roll life," the singer, who first dyed her hair in June, told People Magazine.

"It's so funny, these two lives that I lead."

While her bright blue up-do took fans by surprise Juliette, is far from the first star to dip into their coloring box and emerge looking like Rainbow Brite!

‘Tis the season to play with your make-up – try some new colors and live it up a bit!

We love the Color Play 5-in-1 summer season palette from Sephora with five interchangeable color “stories” customized to fit the portable slim case.

Each of the five trays holds 10 velvety powder eye shadows, 2 creamy lip colors and one soft powder blush for a complete face that harmonizes and flatters all skin tones.

If you’ve always stuck with the “browns”, maybe try the” Tango in Buenos Aires” – a gorgeous mix of blues and greens; or the
“Dinner in Paris” – a tonal mix of chic grays and blacks which we tried for a smokey night-look.

Check out the colors!

The Sephora Color Play 5-in-1 Palette is $29.50 (a $150 value if you bought all these colors separately) and is available online or in all Sephora stores.
