Graph Colorize

If you've ever wanted your Obsidian graph view to actually tell you something at a glance, this rewrites the colorGroups in graph.json to tint nodes by tag, folder, or visibility level. It scans your vault for the most common tags or categories, assigns a colorblind-friendly palette, and merges the settings without clobbering your existing graph physics or filters. The best part is it backs up first and warns you if Obsidian is open, since Obsidian loves to overwrite graph.json on close. Supports tag-based coloring, folder-based, visibility highlighting, or a combination. Honest take: this should have been a native Obsidian feature years ago.

Graph Colorize — Color-code the Obsidian Graph View

You are rewriting $OBSIDIAN_VAULT_PATH/.obsidian/graph.json so Obsidian's graph view tints nodes by tag, folder, or visibility.

Obsidian stores graph settings in <vault>/.obsidian/graph.json. The colorGroups array is a list of {query, color} pairs; the first matching query wins per node. Queries use Obsidian's search syntax: tag:#foo, path:"concepts", file:foo, etc. Color is {"a": 1, "rgb": <packed-int>} where the int is (R << 16) | (G << 8) | B.

Before You Start

Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH.
Confirm $OBSIDIAN_VAULT_PATH/.obsidian/ exists. If it doesn't, the vault has never been opened in Obsidian — tell the user to open the vault once in Obsidian, then re-run.
Warn the user if Obsidian is likely open: Obsidian overwrites graph.json on close. Tell them to close the vault first, or be ready to reload (Cmd/Ctrl+R) and not touch the graph settings until they reload.
