Naturally boost your blonde with Kloss-style babylights.

Williams' babylights bring a natural, sunkissed touch to her brunette strands.

Supersubtle babylights add just the right amount of dimension to dark hair.

"For autumn and winter, expect to see a darker red palette becoming popular," forecasts Garcia. If you're looking for a bold, high-fashion switch-up, try a vibrant oxblood shade. (Think: The color of Boston Baked Beans candy).

"Not everyone can pull off such a bold look -- the client must be edgy," says de Souza. "But on the right person, it can look phenomenal." On how to achieve the look, de Souza says that if the starting point is natural hair, it might as simple as getting a single-process color. For a more vibrant result, it might take two. "If the client has colored hair already, and if it's darker than the shade desired, a removal session will have to be done," he explains. "It all depends on the client's starting point."

The downside to such a vibrant, unnatural red is that it requires a bigger time commitment. "It's a high-risk fade color, so upkeep may be more frequent," explains Woods. Clients who go oxblood should be prepared to stop by the salon every three to four weeks for a hair gloss. This will keep the bold fall hair color looking "fresh and intense," says de Souza.
