The impossible was just realized for fans of Korean pop group BTS. After years of keeping his hair dark, the youngest member, Jungkook, dyed his hair a bright shade of pinkish-red. He showed off his new look at the Lotte Family Concert, leaving ARMYs (as the group's fans are lovingly called) on Twitter absolutely stunned. I like to think of the new shade as "dragonfruit red," and I think it's about to become a new summer hair-color trend.

Vivid red hair has been popular among K-pop stars over the past two years. However, I think I speak for ARMYs across the world when I say that Jungkook is the last idol anyone would expect to color his hair such a shocking red shade. This hair-color development is just as exciting as when everyone in BTS dyed their hair black for the group's latest album, Love Yourself: Tear.

And Jungkook isn't the only member to debut a new dye job at the concert in Seoul. Jin and V went back to blonde once again. (Long live, Blonde Jin.) Jimin and RM now have variations of golden-brown hair. Suga and J-Hope, on the other hand, are sticking with black. However, many have pointed out that Suga now has an undercut.

I recently did a deep dive for Allure on how, when a K-pop star dyes their hair a new bright hue, it's a signal that the group has something major in the works. What do you think BTS is brewing? My guess: A new music video is in the works. No matter what BTS has up its sleeve, I'm looking for eventual selfies the members will post on Twitter of their new looks.
