Replit — design system & UI screens

Dev Tools · 1 screen · 8 sections · replit.com

This is a web platform for building applications and shipping products quickly. The page showcases Agent 4, a tool for rapidly building and deploying apps with features for designing freely, moving faster, and building together. The layout uses a hero section with a call-to-action form at the top, followed by feature highlight sections with rounded card blocks in coral, orange, and gray, social proof from trusted companies, a four-tier pricing table, and closing sections for testimonials and a final CTA button.

Decoded design system

Replit's decoded design system: background #FAF6F1, text #2F3034, accent #FF3C00, link #FF3C00, primary #2492FF; type scale h1 64px / h2 60px / body 28px; 4px spacing base; 8px base radius. The single interactive/action color is #FF3C00 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FAF6F1`
surface	`#EDEAE5`
border	`#DBD8D4`
text	`#2F3034`
text_muted	`#7C7B7B`
primary	`#2492FF`
accent	`#FF3C00`
link	`#FF3C00`
secondary	`#FFB199`
button_bg	`#FF3C00`
button_text	`#FFFFFF`

Using these colors

Action color #FF3C00 — the single interactive color; only on things you click or must notice, never large fills.
accent, link, button_bg are all #FF3C00 — one role, not several (the action color).
accent #FF3C00 — 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 #2492FF — a brand color — but the call-to-action uses #FF3C00, not this.
secondary #FFB199 — 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.
