Hume AI — design system & UI screens

AI · 1 screen · 9 sections · hume.ai

A warm cream (#F7F3EC) landing page for a voice-AI research lab, centered single-column with a thin-weight hero headline where "Emotional Intelligence" is set in a pink-to-purple gradient. The signature element is the recurring flowing pink-purple-orange line-wave gradient art — first as a topographic ribbon banner under the hero, then as a soft radial bloom behind the closing CTA. A standout mid-page block pairs a horizontal bar benchmark chart (TTS model comparison with tabs: Combined / Listenability / Audio Quality / Smoothness) against a "blog post" card, anchoring the page in real data rather than generic marketing imagery.

Decoded design system

Hume AI's decoded design system: background #FFF9F3, text #222222, accent #FFFAF4, link #FCE0EE, primary #E6D1ED; type scale h1 48px / h2 30px / body 16px; 8px spacing base; 0px base radius. The single interactive/action color is #FFFAF4 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFF9F3`
surface	`#F1ECE6`
border	`#DDD8D3`
text	`#222222`
text_muted	`#757371`
primary	`#E6D1ED`
accent	`#FFFAF4`
link	`#FCE0EE`
secondary	`#FFDFB8`
button_bg	`#FFFAF4`
button_text	`#FFFFFF`

Using these colors

Action color #FFFAF4 — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #FFFAF4 — one role, not several (the action color).
accent #FFFAF4 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
primary #E6D1ED — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #FFFAF4).
link #FCE0EE — fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #FFDFB8 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
