Synthwave as a visual style emerged alongside the music genre of the same name in the early 2010s. Producers like Kavinsky, Perturbator, and Carpenter Brut were creating electronic music that sounded like imaginary 1980s film soundtracks, and the album art followed suit: chrome lettering, sunset gradients, wireframe landscapes, DeLoreans.
The look drew on genuine 80s sources -- Tron's glowing circuits, the neon signage of Miami Vice, the airbrush art of Syd Mead and Hajime Sorayama -- but filtered them through 2010s nostalgia into something more stylized than the originals ever were. By 2016, "synthwave aesthetic" had become a recognizable genre on Tumblr, Reddit, and design communities.
On the web, the style peaked around 2018-2020, when CSS grid, custom properties, and performant box-shadows made it feasible to build full-page neon experiences without canvas or WebGL. It remains one of the most distinctive dark-mode aesthetics, trading the restraint of typical dark UI for unapologetic atmosphere.
