Strava. A single orange highlighter mark against black-and-white print.

Strava's design reads like an athlete's logbook printed on warm paper: a stark white canvas warmed by off-white surfaces and a disciplined near-black text palette, with one bolt of vivid orange that signals every primary action. The interface is deliberately flat — no gradients, no shadows, no decorative chrome — letting full-bleed photography of cyclists, runners, and hikers in motion carry all the emotional weight. The custom Boathouse typeface and tight, slightly humanist letterforms give the system a print-publication quality rather than a typical SaaS feel. Sharp 4px corners on every interactive element, warm-toned grays instead of cool ones, and an almost monastic restraint with color (one orange, one link blue) create a visual hierarchy where the orange CTA always wins attention without ever needing elevation or glow.
