# Resend — Style Reference
> Resend's marketing surfaces sit on a near-pure black canvas with off-white
text and a single signature color — the deep editorial-serif Domaine
Display headline mark — that gives an otherwise utilitarian developer-tool
brand its print-magazine confidence. The system pairs Domaine Display
(oversized 76px–96px serif, ss01/ss04/ss11 features on) with ABC Favorit
for body and Inter for UI. Surfaces rely on subtle 6–9% opacity gradient
glows, hairline 1px borders made from translucent white, and a strict
rounded-12px container vocabulary. There is no decorative chrome — just
type, code, and atmospheric depth.
