Hume AI reads as a scientific pastel instrument panel: a near-white laboratory canvas where the only hard mark is a near-black #222222, and color enters as soft watercolor washes — rose, lavender, peach, mint, sky — that visualize data rather than decorate it. The headline typographic move is tight, low-contrast Fellix at 36–48px with negative tracking, set in a weight that whispers rather than shouts, framing emotional intelligence as measured restraint. Components are pill-shaped or softly rounded (8/12/16/24px radii), borders are invisible or hairline, shadows are absent — surfaces separate by hue and whitespace, not elevation. Monospace PP Fraktion Mono appears as the 'lab label' voice: uppercase column headers, tag chips, and data annotations carry a positive +0.025em tracking that contrasts the display sans's tight -0.025em. The overall rhythm is centered, generous, and editorial — sections breathe with 48–64px gaps, content never crowds, and the only saturated accent (#c094e4 violet) lives inside data bars and brand moments, never on chrome.
