Google Calendar color coding: event colors, calendar colors, and ideas

Short answer: To change one event's color on a computer, right click the event, then pick a color. When you create an event, you can also choose the color. On Android or iPhone and iPad, open the event, tap Edit, scroll, select a color, and tap Save. People will not see that event color unless they can make changes on your calendar. To change a whole calendar's color, open Google Calendar on a computer, find the calendar under My calendars, click Options, then pick a color or Add custom color. Help does not document a hex color for events, color-coding tasks, colors by day, or colors by rule.

Resync writes private Busy holds onto your mirror calendars and does not set a color on those holds, so they take the mirror calendar's color. Color the mirror calendar to color the holds. It currently syncs Google calendars only.

Event color vs calendar color

Google Calendar Help separates the color of one event from the color of a whole calendar.

Event color: a color you pick on an event you can edit. Help says people will not be able to see the color you set for events unless you have given them permission to make changes on your calendar.
Calendar color: the color of that calendar in My calendars. Events without their own event color show this color. People who can see the calendar see this color even when they cannot make changes.

If a color looks wrong to someone else, they are usually seeing the calendar color. Your event color is generally only visible to you and to people who can make changes. Help is explicit about that limit; it does not say event colors are hidden from you on other devices you are signed into.

Change an event's color

Google Calendar Help says: when you are creating an event, you can choose the color that event will show as in your calendars.

On a computer, for an existing event:

On your computer, open Google Calendar.
Right click an existing event. Then, pick a color.

On Android:

On your Android phone, open the Calendar app.
Tap on an existing event.
Tap Edit.
Scroll, select a color.
Tap Save.

On iPhone or iPad:

On your iPhone or iPad, open the Calendar app.
Tap on an existing event.
Tap Edit.
Scroll, select a color.
Tap Save.

Focus time is a special event type. Focus time Help documents Edit, then Color, then Save, and says your color selection is saved for future focus time events. Eligible work or school accounts only. See the focus time guide.

Change a calendar's color

Google Calendar Help documents changing a calendar's color on a computer. The Android and iPhone pages still list those computer steps. Help does not document a separate calendar-color path in the Calendar app.

On your computer, open Google Calendar.
On the left side of the page, under "My calendars," find your calendar.
Next to your calendar, click Options.
Pick the color for your calendar or click Add custom color.

Help names Add custom color for a calendar on a computer. It does not document a hex field, and it does not document Add custom color on a single event.

On a computer you can also change how event text looks: Settings, then Appearance, then Modern (white text) or Classic (black text). That color set is computer-only and needs a Light background. It does not change which color an event or calendar uses.

Color coding ideas

These are suggestions, not a Google color scheme. Help documents event colors and calendar colors. It does not assign official colors to work, personal, focus, meetings, travel, or holds.

Use	Suggestion	Why
Work	Give your work calendar one color on a computer: Options next to the calendar, then pick a color.	Calendar color is what other people see unless they can make changes. That stays put as events come and go.
Personal	Give your personal calendar a different color the same way. Overlay both calendars in one view.	Each calendar keeps its color. Seeing both does not copy events or block the other account.
Focus	Color focus blocks you create with the event-color steps, or use Focus time's Edit → Color control.	Event colors stay hidden from people who cannot make changes. Focus time Help says that color is saved for future focus time events.
Meetings	On events you created, right click on a computer or Edit on Android and iPhone, then pick a color.	That is a personal overlay. Guests and people with view-only access still see the calendar color.
Travel	Put travel on its own calendar and color that calendar on a computer.	Help does not document a travel color, a color for each day, or a rule that paints travel automatically.
Holds	Color the mirror calendar that receives Resync Busy holds. Do not color each hold.	Resync does not set a color on holds, so they take the mirror calendar's color. Coloring a hold is treated as an edit.

Work

Suggestion: Give your work calendar one color on a computer: Options next to the calendar, then pick a color.
Why: Calendar color is what other people see unless they can make changes. That stays put as events come and go.

Personal

Suggestion: Give your personal calendar a different color the same way. Overlay both calendars in one view.
Why: Each calendar keeps its color. Seeing both does not copy events or block the other account.

Focus

Suggestion: Color focus blocks you create with the event-color steps, or use Focus time's Edit → Color control.
Why: Event colors stay hidden from people who cannot make changes. Focus time Help says that color is saved for future focus time events.

Meetings

Suggestion: On events you created, right click on a computer or Edit on Android and iPhone, then pick a color.
Why: That is a personal overlay. Guests and people with view-only access still see the calendar color.

Travel

Suggestion: Put travel on its own calendar and color that calendar on a computer.
Why: Help does not document a travel color, a color for each day, or a rule that paints travel automatically.

Holds

Suggestion: Color the mirror calendar that receives Resync Busy holds. Do not color each hold.
Why: Resync does not set a color on holds, so they take the mirror calendar's color. Coloring a hold is treated as an edit.

Color-by-calendar is the durable approach: each calendar keeps one color that other people can see. Event colors are a personal overlay. Help does not document coloring tasks, coloring by day of the week, colors by rule, or a color-coding extension.

Multiple calendars and accounts

If you overlay several calendars, each calendar's color is how you tell them apart. That is more stable than coloring individual events, because event colors stay hidden from people who cannot make changes.

Web Calendar is one Google Account per browser tab. The Calendar app can show several signed-in accounts together. Seeing both does not copy events or stop double-booking. Those limits are in the multiple accounts guide and the merge calendars guide.

A shared calendar you do not own still has a color in your list. Help documents changing a calendar's color from Options on a computer. That does not change the owner's calendar color for everyone else.

Private and Show as busy hide details. They do not set a color. See the private events guide and the show busy instead of details guide.

Color coding not working

Most "color coding not working" reports are a visibility limit, the wrong account, or a control Help only documents on a computer.

What you see	Likely cause	Fix
Other people still see the calendar color	Event colors you set are hidden unless those people can make changes on your calendar.	Color the calendar if others should see the color. Or give them a Make changes permission if they should see your event colors.
Wrong Google account	Web Calendar is one account per browser tab. A color you set in another account will not show here.	Open calendar.google.com in the account that owns the calendar. On a phone, confirm that account is signed in and the calendar is turned on.
The event is someone else's invite	Help documents picking a color on an event you can edit. If you cannot edit, you may not find those controls.	Open the event and look for Edit. If you only have Remove or a response, color your own copy of the calendar instead.
Computer and phone look different	The Modern and Classic event color set is computer-only and needs a Light background.	On a computer: Settings → Appearance. Choose Modern or Classic. Help does not document that color set in the Calendar app.
No calendar color control on Android or iPhone	Help documents changing a calendar's color on a computer. The Android and iPhone pages still list those computer steps.	Open Google Calendar on a computer. Under My calendars, click Options, then pick a color or Add custom color.
A third-party app is syncing the calendar	Help's create-event troubleshooting says a third-party sync can interfere.	Try turning off that sync, then sign out of Google Calendar, close the browser, and sign in again with https.
No hex color, task color, or color by day	Help documents Add custom color for calendars on a computer. It does not document hex for events, coloring tasks, or coloring by day or rule.	Use a separate calendar for a color others should see. Do not look for an undocumented hex field, task color, or weekday rule.
Resync Busy holds are the wrong color	Resync does not set a color on the holds it writes, so they take the mirror calendar's color.	Color the mirror calendar on a computer. Do not color a hold; Resync treats that as an edit and does not recreate it.

Other people still see the calendar color

Likely cause: Event colors you set are hidden unless those people can make changes on your calendar.
Fix: Color the calendar if others should see the color. Or give them a Make changes permission if they should see your event colors.

Wrong Google account

Likely cause: Web Calendar is one account per browser tab. A color you set in another account will not show here.
Fix: Open calendar.google.com in the account that owns the calendar. On a phone, confirm that account is signed in and the calendar is turned on.

The event is someone else's invite

Likely cause: Help documents picking a color on an event you can edit. If you cannot edit, you may not find those controls.
Fix: Open the event and look for Edit. If you only have Remove or a response, color your own copy of the calendar instead.

Computer and phone look different

Likely cause: The Modern and Classic event color set is computer-only and needs a Light background.
Fix: On a computer: Settings → Appearance. Choose Modern or Classic. Help does not document that color set in the Calendar app.

No calendar color control on Android or iPhone

Likely cause: Help documents changing a calendar's color on a computer. The Android and iPhone pages still list those computer steps.
Fix: Open Google Calendar on a computer. Under My calendars, click Options, then pick a color or Add custom color.

A third-party app is syncing the calendar

Likely cause: Help's create-event troubleshooting says a third-party sync can interfere.
Fix: Try turning off that sync, then sign out of Google Calendar, close the browser, and sign in again with https.

No hex color, task color, or color by day

Likely cause: Help documents Add custom color for calendars on a computer. It does not document hex for events, coloring tasks, or coloring by day or rule.
Fix: Use a separate calendar for a color others should see. Do not look for an undocumented hex field, task color, or weekday rule.

Resync Busy holds are the wrong color

Likely cause: Resync does not set a color on the holds it writes, so they take the mirror calendar's color.
Fix: Color the mirror calendar on a computer. Do not color a hold; Resync treats that as an edit and does not recreate it.

Google Calendar Help steps checked Nov 3, 2026. Cited from Create an event, Create a new calendar, Change event color set & density, and Choose what others can do with your calendar.

When Resync helps (and when it does not)

Use the steps above to color events you can edit and calendars you can open on a computer. Resync does not color-code your existing events, copy source event colors, or offer hex colors, task colors, or colors by day. It does not sync Outlook, Apple Calendar, or iCloud.

Use Resync when you need the same busy time on another of your Google calendars. Resync only creates Google-only private Busy holds between a user's own Google Calendars. Holds are titled Busy. Resync does not set a color on those holds, so they take the mirror calendar's color. Color the mirror calendar to color the holds. It currently syncs Google calendars only. $1.50/month or $9/year after a 30-day free trial, no credit card required.

Holds are titled Busy. Description, location, attendees, and conference data are left empty, so source meeting details stay on the source calendar.
Resync does not set a color on the holds it writes. Source event colors are not copied. The hold uses the mirror calendar's color until you change that calendar.
If you change the color of a hold, Resync treats that as an edit and does not recreate it for the same source event on that mirror.
If a source event moves, Resync updates the hold. If the event is cancelled, marked free, declined, or is a working-location event, Resync does not keep a hold.
Resync looks 90 days ahead when it reads source events. A polling fallback also runs about every 5 minutes. Read-only calendars cannot be mirrors. Resync currently syncs Google calendars only.

Set up Resync

Sign in with GoogleOpen Resync and sign in with the Google account you want as your primary account. You land on setup.
Connect another Google accountChoose Connect another Google account and finish Google's permission screen. Resync needs at least two Google accounts before you can start.
Start syncingWhen a second account is connected, setup shows bidirectional mirroring as the intended default: real events on either side become private busy blocks on the other. Choose Start syncing to open the dashboard.
Mark sources and mirrorsIn Sync configuration, turn on Source to read busy time from a calendar and Mirror to receive Busy holds. A calendar can be both. Read-only calendars cannot be mirrors because Resync needs write access to create holds.

FAQ

How do I change an event color in Google Calendar?

Google Calendar Help says: when you create an event, you can choose the color that event will show as in your calendars. On a computer, right click an existing event, then pick a color. On Android or iPhone and iPad, open the event, tap Edit, scroll, select a color, and tap Save. People will not see the color you set for events unless you have given them permission to make changes on your calendar.

How do I change a Google Calendar's color?

Google Calendar Help documents this on a computer: open Google Calendar, find the calendar under My calendars, click Options next to it, then pick a color or click Add custom color. The Android and iPhone Help pages for creating a calendar still list those computer steps. Help does not document a separate calendar-color path in the Calendar app.

Can other people see the event colors I set?

Usually no. Google Calendar Help says people will not be able to see the color you set for events unless you have given them permission to make changes on your calendar. People who can only see free/busy or event details still see the calendar's color. If you need others to see a color, color the calendar, not the event.

Can I use a hex color, color-code tasks, or color events by day?

Google Calendar Help documents Add custom color for a calendar on a computer. It does not document a hex field for events, a custom color picker on a single event, color-coding tasks, coloring by day of the week, colors by rule, or a color-coding extension. Use a separate calendar when you want a durable color others can see.

Why is Google Calendar color coding not working?

Check the account, the calendar, and whether you can edit the event. Event colors you set are hidden from people who cannot make changes on your calendar, which often looks like the color failed. The Modern and Classic event color set is computer-only and needs a Light background. Help documents calendar color on a computer. If a third-party app syncs the calendar, Help says to try turning off that sync, then sign in again.

Do Resync Busy holds keep the source event color?

No. Resync does not set a color on the private Busy holds it writes, so those holds take the mirror calendar's color. Color the mirror calendar on a computer to color the holds. If you change the color of a hold, Resync treats that as an edit and does not recreate it for the same source event on that mirror. $1.50/month or $9/year after a 30-day free trial, no credit card required.
