Episode Details

When Tailwind CSS creator Adam Watten picked Indigo 500 as a default button color in 2020, he had no idea he was accidentally painting every AI-generated website the same shade. Today, AI design tools have converged on an eerie visual monoculture—purple gradients, Inter typeface, rounded cards, and three-column feature boxes appear everywhere. We trace how one arbitrary design choice rippled through training data to create a world where "AI website" looks identical.
