Amp Up Your Color

Gone are the My So-Called Life days of Claire Danes's one-dimensional, Crayola-red strands. Now her color still has a touch of strawberry but is considerably lightened. "I love that rosy golden tone," says Amy Huson, a colorist at the Marie Robinson Salon.

Almost white-platinum on the sides and a tad darker on the top, Michelle Williams's hair is a head-turner, with her cut and color perfectly in-sync. "Platinum hair always looks better when it's shorter and edgier," says stylist Rita Hazan.

Hello, Old Hollywood! Big blond waves like Blake Lively's have always been glamorous starlet material, but "the honey blond is a great way to tone down a lighter blond for fall," says Huson.

Though she's not a natural redhead, Emma Stone became known for her "gorgeous, natural-looking red hair," says stylist Tracy Cunningham -- so when Stone's colorist took Emma blond, the look had a lot to live up to. Thankfully, it did. "Now her blond is amazing too," says Cunningham.

Connie Britton's hair is darker at the crown and underneath, with lighter highlights from her eyes to her chin, drawing attention to her gorgeous face (Texas forever!). To transition too-summery blond to fall "Try sun-kissed highlights in a slightly deeper golden tone, and richen up your base under the highlights," says Huson.

Cool and edgy, Gwyneth Paltrow's ash blond shade and dark brown roots continue to be a hit. "It's my most requested look," says Cunningham.

Mila Kunis's hair is a rich brown throughout, with a deeper espresso shade at the crown that graduates to a slightly warmer, lighter shade from her cheekbones to the ends -- and it's glossy throughout. "The richer the brunette shade, the better it looks," says Huson.

You can't argue with Catherine, Duchess of Cambridge's sartorial choices -- or her haircolor. It's a great step for those with dirty blond or light brown hair to look less summery. "Simply tone down one to two shades darker and warmer." says Hazan. "You'll be in your same color family but with more fall-appropriate tones."

The easiest way to bring a little of that sun-kissed summer spirit to fall is with very thin, natural-looking highlights (no skunk streaks!), like the lighter strands that make Emmy Rossum's chestnut hair look multi-dimensional. "Have your colorist add a variety of warmer browns and beiges," says Cunningham.

As Lady Mary, Michelle Dockery likes to try new things (hello, hunky Turkish house guest!) and the same goes for her dark chocolate curls. It's easy to achieve the same saturated color. "Deep, rich brunette shades are trending for fall. You can still stay close to your same color -- just deepen the tone a little," says Huson.
