Messenger Mobile — design system & UI screens

Communication · 13 screens · messenger.com

A vibrant chat interface showing a group conversation thread. The main content area displays a shared photo with a message bubble overlay and engagement reactions (heart, laughing emoji, count). Below is an active conversation with playful decorative illustrations and emoji elements. The design uses a light blue header with avatars, action buttons (call/video), and a green landscape-themed background with botanical illustrations. Official Google Play listing screenshot.

Decoded design system

Messenger Mobile's decoded design system: background #FFFFFF, text #000000, accent #26877F, link #26877F, primary #26877F; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #26877F — 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	`#26877F`
accent	`#26877F`
link	`#26877F`
button_bg	`#26877F`
button_text	`#FFFFFF`

Using these colors

Action color #26877F — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #26877F — one role, not several (the action color).
accent #26877F — 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.
