Calendar Color Rules

Automatic coloring rules, manual overrides, and full color bars for Google Calendar.

Calendar Color Rules helps you organize Google Calendar automatically, using simple keyword-based rules — no manual coloring required. Key features: - Automatic coloring rules: color events by keyword matches in the title - Manual per-event override: fine-tune any single event's color with a full color picker, with a live preview directly on the calendar - Default color for new events: set a fallback color applied automatically when no rule matches - Focus mode: dim every event that doesn't match a chosen rule, so what matters stands out at a glance - Import/export your rules as a JSON file, to back them up or move them to another computer - Color breakdown: see how your upcoming events are distributed by color Privacy first: Calendar Color Rules runs entirely in your browser. It has no backend server, sends no data anywhere, and only reads the calendar.google.com page you're already viewing to apply your color rules. Your rules and preferences are stored locally via Chrome's built-in sync storage. Free to use. If you find it useful, you can support future development with an optional, one-time donation from the extension's popup. Questions or feature requests?
