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.
