Understand Acrobat's Commenting Color Limitations

Adobe Acrobat automatically assigns colors to the author name in the commenting interface, and this setting cannot be manually overridden.

Adobe Acrobat does not provide a user preference for changing the color of the author's name shown in the commenting sidebar. The application automatically selects this color based on document properties, such as differentiating multiple reviewers.

While you cannot change the text color of the author's name itself, you can customize other aspects of your annotations, such as the border, fill color, and opacity of the comment shapes and highlights.

1
Verify Commenting Preferences

Navigate to 'Edit' > 'Preferences' > 'Commenting' (Windows) or 'Acrobat' > 'Preferences' > 'Commenting' (Mac) to view all available customization settings.

2
Change Annotation Color Instead

To change the color of the actual comment icon or highlight, right-click the annotation in the document, select 'Properties', and choose a new color under the 'Appearance' tab.

Feature Request Status: Adobe previously declined a community feature request to make the author name color match the comment color in the sidebar. Customizing this specific UI element remains unsupported.
