Pirsch Analytics. Sunlit paper notebook with highlighter swatches.

Pirsch uses a warm paper-notebook language: a soft cream canvas (#f8f5ed) replaces the usual SaaS white, and the only chromatic punctuation is a sunshine yellow (#ffda6e) that reads as a highlighter, not a brand stamp. Almost the entire interface is achromatic — ink-black text and 1px hairline borders do the structural work that shadows and fills do elsewhere. Typography is a single family (DM Sans) running from a whisper at 14px to a commanding 64px display, with generous 8px-grid breathing room and unusually rounded 24px corners that make cards feel like sticky notes. Green (#6ece9d) appears sparingly as a status/availability signal (happy-customer badge, theme-toggle dot) and never competes with yellow. The overall feel is editorial and tactile — closer to a printed report than a dashboard.
