The anime Jellyfish Can't Swim in the Night features characters with outlandish hair colors, a detail cleverly tied to their characterization. Three of the four main characters changed their natural hair color to match their show counterparts, reflecting the theme of reinvention. This deliberate choice not only enhances character designs but also serves as an intentional storytelling device, challenging the common trope of exotic hair colors in anime. The recurring motif of hair dye symbolizes the characters' desire to escape their past and reinvent themselves. This unconventional use of character design adds depth to the narrative, highlighting the value of visual elements in storytelling. Jellyfish Can't Swim in the Night creatively explores how something as simple as changing hair color can represent significant character development.
