Railway — design system & UI screens

Dev Tools · 2 screens · 18 sections · railway.com

A long-scroll dark marketing page opening with a centered hero headline over a painterly twilight-cloud illustration and a floating product UI card showing a GitHub deploy modal. Below, alternating left-text/right-screenshot feature sections, a logo wall, testimonial cards, and a striking split-flap mechanical counter board displaying live deploy/usage stats anchor the visual hierarchy.

Decoded design system

Railway's decoded design system: background #13111C, text #ECECEE, accent #553F83, link #291839, primary #1F132A; type scale h1 54px / h2 40px / body 18px; 8px spacing base; 6px base radius. The single interactive/action color is #553F83 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#13111C`
surface	`#201E28`
border	`#33313B`
text	`#ECECEE`
text_muted	`#99989E`
primary	`#1F132A`
accent	`#553F83`
link	`#291839`
secondary	`#553F83`
button_bg	`#553F83`
button_text	`#FFFFFF`

Using these colors

Action color #553F83 — the single interactive color; only on things you click or must notice, never large fills.
accent, secondary, button_bg are all #553F83 — one role, not several (the action color).
accent #553F83 — 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 #1F132A — a brand color — but the call-to-action uses #553F83, not this.
link #291839 — 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).
