Amplitude — design system & UI screens

Analytics · 1 screen · 11 sections · amplitude.com

An AI analytics platform for understanding customer behavior and deriving insights from business data. The page uses a hero-driven layout with prominent CTAs, featuring a series of stacked card sections showcasing key features (customer insights, faster iteration, unified data), industry trust badges, metrics-based value props, and customer testimonial cards. The design employs a gradient color palette transitioning from blue to pink, with alternating light and dark sections to create visual rhythm.

Decoded design system

Amplitude's decoded design system: background #FFFFFF, text #000000, accent #000000, link #BCD0FB, primary #1E61F0; type scale h1 60px / h2 40px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#1E61F0`
accent	`#000000`
link	`#BCD0FB`
secondary	`#B0C8FA`
button_bg	`#000000`
button_text	`#FFFFFF`

Using these colors

Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #000000 — one role, not several (the action color).
accent #000000 — 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 #1E61F0 — a brand color — but the call-to-action uses #000000, not this.
link #BCD0FB — fails contrast on the background (~1.5:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #B0C8FA — 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.
