Patterna

A generative geometric pattern studio. Pick one of seventy-two equation families, then Generate for new geometry and Recolor for new palettes. Every pattern comes from a seed, so the URL reproduces it exactly — and geometry and color are independent, so recoloring never disturbs the structure.

Palettes are built from color-harmony rules in HSL. Export re-renders from the equations at up to 4K — never upscaled. Runs entirely in your browser: no backend, no API calls, no accounts.
