Set author name and comment color in Pages on Mac
You can specify the author name and color that are used to identify your comments and the edits you make when change tracking is turned on. Each person uses a different color.
Set your author name
You can change the name that appears in the comments you make in Pages and for your tracked changes. The new name appears the next time you comment in a document or make tracked changes, as well as in comments and changes you made previously.
Choose Pages > Settings (from the Pages menu at the top of your screen).
Click General at the top of the settings window.
Enter a name in the Author field, then close the settings window.
The name doesn’t apply to documents that are shared with others. For shared documents, the name that appears in comments and in the participant list is the name you use with your Apple ID. To change the name (without changing your Apple ID), visit the Apple ID account page. After you sign in, click Edit to the right of your account information, then make your changes and click Done.
Important: If you change the name used with your Apple ID, the name appears in all apps and other locations that use your Apple ID.
If you stop sharing a document, the author name in comments and change tracking reverts to the author name you set in Pages settings.
Change your author color
Your author color is associated with the changes you make and the comments you add to a document. You can change your author color at any time.
Choose View > Comments & Changes > Author Color (from the View menu at the top of your screen), then choose a color.
If you have a document open, all of your comments and changes in the document switch to the new color, and any new documents you create using the same author name use the new color.
If you’re using iCloud when you make the change, any documents you shared or joined using the same Apple ID are also updated with the new color.
When change tracking is on, you can also click in the review toolbar, then choose an author color.
Note: You must add a comment or make a change using the new color to save it in Pages settings. If you close the document without making any changes, the author color reverts back to the previous color.
