Hello, Gorgeous! See The Hunger Games's Julianne Moore's Best Beauty Moments

Julianne Moore is a chameleon--a hair chameleon, if you want to get specific. For her many roles, the actress has underwent color changes, from donning a vibrant shade of blond for a part in Maps to the Stars, to her equally eye-catching silver strands in the upcoming The Hunger Games: Mockingjay -- Part 1.

Moore, who plays the powerful President Alma Coin in the last film of the Hunger Games trilogy, is no stranger to experimenting, whether it means ditching her signature red hair or rocking a hot pink lip on the red carpet. So, what's the star's best beauty tip? "Less really is more. The idea behind makeup is to enhance whatever color or contours you have in your face," the actress tells friend Olivia Munn during an interview for InStyle. "I'm a big believer in that. And don't use to much powder; powder is really aging. I've made that mistake myself." Sound advice!
