Stripe's design language is the visual shorthand for "trustworthy fintech." Built on a near-white canvas, a signature indigo purple, and generous whitespace, it communicates competence without coldness. Gradient mesh heroes — swirling blends of indigo, violet, and teal — add warmth and dimensionality to an otherwise restrained palette.

The system pairs Inter's neutral precision with soft shadows, rounded cards, and breathable layouts. Every element earns its place through clarity, not decoration. Stripe proves that a payments company can feel as considered as a design studio.
