HeyGen turns AI video into a spectacle: ABC Solar Display at 80px dominates whole viewports, avatar videos autoplay as the true hero imagery, and a signal cyan #00C3FF on 12px-radius buttons keeps the energy synthetic and bright. TT Norms Pro handles the 16px supporting text while scale does the selling — a creator tool that shouts in display type because its product literally speaks.

Tokens

HeyGen's decoded design system: background #FFFFFF, text #0A0A0B, accent #00C3FF, link #00C3FF, primary #DFF8FF; type scale h1 80px / h2 56px / body 80px; 4px spacing base; 10px base radius. The single interactive/action color is #00C3FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F0F0`
border	`#DADADA`
text	`#0A0A0B`
text_muted	`#676767`

accent	`#00C3FF`
link	`#00C3FF`
secondary	`#F9ECFF`
button_bg	`#00C3FF`
button_text	`#171717`

Using these colors

Action color #00C3FF — the single interactive color; only on things you click or must notice, never large fills.
accent, link, button_bg are all #00C3FF — one role, not several (the action color).
accent #00C3FF — 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 #DFF8FF — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #00C3FF).
secondary #F9ECFF — 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.
