There's no denying that this spring is all about color. Runways all over the world featured brights in every shade. In a series titled "Color of the Week," StyleList will outline the most popular hues -- as declared by Pantone, world-renowned color authority -- with designer inspiration, celebrity examples, beauty tips and more. For our first installment we present the No. 1 color this season: #18-2120, also known as honeysuckle.

Jason Wu, Christopher Kane, Alber Elbaz and Gianfranco Ferré are all extraordinary designers with very different tastes. However, the four men gave us déjà vu as they all sent models down the runway wearing the same dynamic reddish pink. It's no wonder that the encouraging and uplifting color translated so well from high fashion to everyday wears. Stores like Forever 21 and Topshop both highlighted the hue for spring, and stars like Julianne Moore couldn't get enough of it.

And it must come as no surprise that the ladies of our Blogger Network are up on the trend: Chloe from Beckerman Bite Plate incorporated a honeysuckle vintage hat into her eclectic ensemble. And Lindsey from Saucy Glossie was happy to layer a bright button-down into her perfectly styled Converse One-Star outfit for Target.

Honeysuckle gives women of all skin tones something to smile about. The hue typically balances out a blond hair color and keeps skin looking warm and dewy for fairer skin tones. We love the example of Hollywood's leading ladies: When wearing a honeysuckle lip, stick to a simple shade and pair with bold for eyes.
