It may still be sunny in California where Madelain Petsch lives, but she's clearly ready for fall with her latest manicure. Just in time for the 1st of October, the Riverdale [2] actor has transitioned her nails for the next season [3] by putting a fall-toned twist on the Skittles nail-art trend [4].

Petsch gave us a peek at her mani via Instagram Stories on Sept. 29. In the photo of her smiling, which she wrote "Happy" across in white lettering, her almond-shaped manicure can be spotted as she blocks the sun with her hand. Each nail has a different shade [5] of beige, peach, or brown nail polish on it, giving a gradient effect [6] across her five fingers.

The Skittles nail-art trend went viral a few years ago, and social media was subsequently flooded with multicolored manis in a rainbow of hues. Traditionally, the nails are meant to resemble the bright candy, but the trend has evolved since then to include an array of colors. As far as nail-art trends go, Skittles manicures are easy to do at home — once you decide on your color palette, all you need is five different shades of nail polish.

Take a look at Petsch's fall-toned skittles nail art ahead, and see for yourself just how simple the nail look is.
