Though she's dabbled in lighter and brighter shades of blonde, this cool, neutral shade is Cara Delevingne's signature. Another eye-catching variation of bronde, it's a beautiful complement to those with cool undertones. Pro tip: To determine your undertone, look at the inside of your wrist! If your veins look blue or purple, you have cool undertones and if they're on the greener side, you have warmer undertones.

The brightest in the bunch, this drool-worthy light brown shade has us dreaming of sandy beaches, ice cold bevies, and lips that don't chap the second we leave the house. A tad more blonde than brown, this sunny shade is incredibly flattering, says Papanikolas, as it can be customized with either cool or warm highlights to suit your skin tone. Supermodel Nina Agdal demonstrates, and we're raising our hands (we know you know the Emoji).

If you were to type bronde into your search bar, chances are Olivia Palermo would be the first (of many a Hollywood face) to pop up. The girl just gets it, and consistently nails the coveted hybrid shade. Oh, and if you're looking to channel Palermo's impeccable shine/gloss/all around unicorn hair situation, Papanikolas recommends a lightweight mist like Matrix Biolage Sugar Shine Illuminating Mist, $20, to create an A-list worthy finish.

Our No. 1 beauty wish? To look like Jennifer Lopez. In the meantime, we'll be coveting the triple threat's signature light brown shade: a warm, tawny hue that Papanikolas cites as "the perfect balance of light brown hair and dark blonde hair." If you have a deep, golden complexion, consider bringing J. Lo to your next salon color sesh. Or at least this picture for some inspiration.
