Ri Ri set the trend with this head-turning hue.

A vibrant red adds some edge to long, wavy strands

Reed shows the soft side of this dramatic fall hair color.

Combine "subtle" and "ombré," you get sombré. So what do you get when a hair color trend combines brunette and blonde shades? You get "bronde," of course.

Bronde is a highly customizable look that uses natural brown as an all-over color, adding babylights and light ends for a more natural, multi-chromatic effect, says Garcia.

The look is more universally flattering than full-on blonde -- so, for those who want to go lighter, but are too cool (or too nervous) to go platinum, this fall hair color gives that California girl vibe without going all the way. It's also a great fall hair color for transitioning out of a harsh ombré style.

Bronde is low-upkeep -- similar to sombré, depending on how natural a look you're going for. But by far the lowest-maintenance version of bronde is the "lived-in color" technique. Pioneered by celebrity colorist Johnny Ramirez, "lived-in color" is a detailed highlighting method that results in a gorgeous, natural bronde, which lasts six months or more.

Instead of going full honey blonde, opt for cool girl Delevingne's subtler blend.
