Bisexual lighting refers to the simultaneous use of pink, purple, and blue light to create a specific neon aesthetic that mirrors the colors of the bisexual pride flag. The term gained widespread traction on social media around 2017, with fans pointing out the color scheme in films like 'Atomic Blonde,' 'The Neon Demon,' and the 'San Junipero' episode of Black Mirror. While some critics and fans argue the lighting is a deliberate visual cue for a character's sexuality, others appreciate it as a purely atmospheric cinematography choice. Today, the meme is used to highlight instances of these colors in pop culture or to ironically 'bi-fy' images by adding neon gradients, celebrating both LGBTQ+ representation and striking visual design.
