Though the Powerpuff design has Y2K roots, its retro style may have origins in the '70s . We've seen a return to retro '60s and '70s aesthetics in recent years, and this bright gradient pattern is right on time.
Even though heart and love-inspired nails are in no way new, this nail design began popping up around Valentine's Day of 2021. These nostalgic red-and-pink heart beams took over our timeline in the format of gel, acrylic, and even press-on sets. In no time, the repeating heart pattern was everywhere and brands such as Wildflower got ahold of the design for their loyal Gen-Z fanbase.
As this nail design extended past Valentine's Day, nail artists began to incorporate other elements from the show such as blue and green heart patterns, the staple colors for Buttercup and Bubbles. @thenailaddict even paid homage to the titular villains, HIM and Mojo Jojo, by getting creative with gradient red and purple sets. Their design calls upon multiple Y2K trends, alternating between classic hearts, glittery "Thrasher"-inspired flames, and yin-yang patterns.
