Google Calendar Color Codes: What Every Color Means and How to Use Them

Google Calendar color codes don't have any built-in meaning — the 11 colors are just labeled palettes you assign yourself. The trick is knowing their names and building a personal system where each color always means the same thing. This guide lists every default Google Calendar color and shows how to turn them into a system you'll actually use.

The 11 default Google Calendar colors

Google ships the same 11 named colors on every calendar. Here they are, roughly light to dark, with the tones most people perceive:

On the web you can also set a custom hex color for a whole calendar via the sidebar's three-dot menu, but the 11 named colors above are the standard set that appears everywhere, including mobile.

Why color-coding helps

A glanceable calendar lets you answer "what kind of day is this?" without reading a single title. Colors group activities by type, energy, or priority — so a wall of meetings is obvious before you've even focused your eyes. Color also survives at small sizes (like the month view) where text is too tiny to read.

Build a personal color system

The goal is consistency: pick a meaning for each color and stick to it. Here's a proven starting framework you can adapt.

1. Decide what dimension to encode

Most people color by one of these:

• Type of activity — meetings vs. focus work vs. personal.
• Project or client — one color per major workstream.
• Energy level — high-focus vs. low-effort vs. recovery.

Pick one dimension. Mixing two (color = both client and energy) breaks down fast.

2. Assign bold colors to what matters most

Reserve high-contrast colors for things you must notice:

• Tomato — hard blocks: focus time, deadlines, "do not book."
• Tangerine / Banana — meetings and collaboration.
• Basil / Sage — personal, health, breaks.
• Peacock / Blueberry — admin, email, shallow work.
• Grape / Lavender — learning, side projects.
• Graphite — tentative, low-stakes, or "ignore."

3. Apply it consistently

• Set a default color per calendar so most events get the right color automatically.
• Override individual events only when they differ from the calendar default.

See how to change event colors for the exact steps to recolor single events and whole calendars.

A sample system you can copy

Keep it sustainable

• Fewer colors win. Three to five meanings are easier to scan than eleven.
• Be honest about overrides. If you're recoloring half your events by hand, your calendar defaults are wrong.
• Review monthly. If a color no longer maps to a real category, retire it.

If you run separate Google and Outlook calendars, nocal merges them into one consistently color-coded timeline — see how.
