Captions — design system & UI screens

AI · 1 screen · 10 sections · captions.ai

Editorial centered hero with bold near-black serif-weight headline "AI that edits like a professional editor would." over a warm peach-to-lavender gradient wash; the signature element is a floating light-glass prompt/editor mockup with a "drag video" upload zone sitting atop a row of four vertical vertical-video thumbnails, framing Captions as a conversational AI editor. Below, the page alternates full-bleed creator-video showcase tiles (Elevate/Paper/Prime style cards), a four-icon feature grid, a monochrome "As seen in" press logo wall, and oversized stat numbers (100K+, 20M, 3M+). Distinctive use of real UGC talking-head footage as the primary visual texture rather than abstract graphics.

Decoded design system

Captions's decoded design system: background #FFFFFF, text #1D1F20, accent #1D1F20, link #D9F8FF, primary #EFFBFF; type scale h1 72px / h2 48px / body 16px; 4px spacing base; 15px base radius. The single interactive/action color is #1D1F20 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F1F1F1`
border	`#DDDDDD`
text	`#1D1F20`
text_muted	`#727474`
primary	`#EFFBFF`
accent	`#1D1F20`
link	`#D9F8FF`
secondary	`#6B7280`
button_bg	`#1D1F20`
button_text	`#FFFFFF`

Using these colors

Action color #1D1F20 — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #1D1F20 — one role, not several (the action color).
accent #1D1F20 — 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 #EFFBFF — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #1D1F20).
link #D9F8FF — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #6B7280 — 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.
