Omarchy theme for Obsidian

An Obsidian theme built from Omarchy colour palettes, with IBM Plex Mono embedded, a long-form writing layout and soft rounded corners.

Build

python3 bin/build.py

Writes theme.css and manifest.json to the repo root (both are committed). Options: --live replaces the matching light or dark palette with the current Omarchy theme colours; the other palette stays bundled. --install also copies the result into every vault listed in ~/.config/obsidian/obsidian.json and selects the theme.

Tests: python3 -m unittest discover -s tests

Install

Copy theme.css and manifest.json into <vault>/.obsidian/themes/Omarchy/, then choose Omarchy under Settings → Appearance → Themes.

Light and dark

Both modes are included: navy and gold from src/colors.toml, and warm paper with navy ink and deep amber from src/colors-light.toml. Choose Light, Dark, or Adapt to system under Obsidian Settings → Appearance → Base color scheme.

Follow Omarchy

Build from the current Omarchy palette and install into your configured vaults:

python3 bin/build.py --live --install

With --live --install, only the vault copies are updated; the committed theme.css and manifest.json in the repo root stay unchanged, so theme switches keep the Git tree clean. Without --live, builds still write the repo files.

To follow future theme changes, save this as obsidian-theme (adjust the repo path if needed):

#!/bin/sh
exec python3 "$HOME/code/obsidian-omarchy-theme/bin/build.py" --live --install

Install it with omarchy hook install theme-set ./obsidian-theme. This copies an executable hook into ~/.config/omarchy/hooks/theme-set.d/. Each theme change rebuilds both blocks, replaces the block matching Omarchy's mode, and installs the result. Use Obsidian's Adapt to system setting to follow system mode.

iPhone
