When several of the most popular online retailers all seem to agree on a handful of summer trends, it's a good indication that you'll soon be seeing them everywhere. Such is the case with a trio of color trends at H&M, Madewell, and Mango. While sifting through the retailers for other stories, I noticed certain hues kept popping up over and over.
These retailers are going all-in on three very specific shades, not just general color families. For starters, while we saw a lot of pastels for spring, summer has turned into the season of cobalt. Dresses, tank tops, blouses, pants—you name it and one of these brands carries it in cobalt blue. Scroll down to shop the three colors trending at H&M, Madewell, and Mango right now, as well as stellar outfit ideas for each shade.
