Obsidian Mobile — design system & UI screens

Productivity · 13 screens · obsidian.md

A note-taking and idea collection app for capturing, organizing, and referencing writing concepts and quotes. The screen displays a single note with a bold headline, hashtag category, source attribution, subheadings with body text, bullet points for key concepts, and a block quote—all with a reading-focused layout, typography hierarchy, and navigation controls at the bottom for browsing and creating notes.

Decoded design system

Obsidian Mobile's decoded design system: background #000000, text #FFFFFF, accent #2D234E, link #2D234E, primary #2D234E; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #2D234E — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0F0F0F`
border	`#262626`
text	`#FFFFFF`
text_muted	`#9E9E9E`
primary	`#2D234E`
accent	`#2D234E`
link	`#2D234E`
button_bg	`#2D234E`
button_text	`#000000`

Using these colors

Action color #2D234E — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #2D234E — one role, not several (the action color).
accent #2D234E — 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.
