Madelaine Petsch [1] gave fans a glimpse of what's to come in the upcoming season of Riverdale [2] through a recent Instagram post, and we learned two things. First, Jason Blossom will be making a haunting return. Second, Cheryl Blossom (Petsch's character on the show)'s signature nail look will also be making a comeback — and inspiring Fall manicures everywhere.

In the video, Petsch zoomed in on her red nail polish colour [3]. The fiery hue is one that manicurist Jin Soon Choi [4] previously told POPSUGAR would be this Fall's biggest trends.

"They are timeless colours that cross from classic to modern and feminine to bold, making them perfect for all Autumn occasions," she said, referring to the shade, as well as its deeper iterations. Her forecast was spot-on, as celebrities [5] (including Rihanna [6], Charlize Theron [7], and Kardashian) have been gravitating toward the colour since the start of the season.

Red nail polish — and the colour red, in general — has been a key part of Petsch's signature look on the show with intention. Camila Mendes [8], who plays Veronica Lodge on the CW original, told POPSUGAR in a recent interview that maintaining these looks is what gives Riverdale its comic book vibe. "It's what keeps the characters iconic and consistent," she said.
