Scenario
Merging multiple PDF files into a single document and reviewing the navigation pane.
Observed behavior
The resulting combined PDF contains bookmarks with inconsistent colors (some are blue, others are gray), which applies to either the bookmark text or the bookmark icons.
Before you start

Identify whether the color inconsistency is affecting the bookmark icons (the small symbols next to the text) or the bookmark text itself, as the troubleshooting steps differ for each scenario.

Solution 1Recommended

Standardize Bookmark Text Color via Appearance Properties

Change the text color of the affected bookmarks to ensure a uniform look across your combined PDF document.

When merging PDFs, the new document inherits the bookmark properties from the source files. If the original authors applied different text colors to their bookmarks, these custom appearances carry over into the combined file.

1
Open the Bookmarks panel

Open the combined PDF document in your PDF editor and expand the Bookmarks navigation pane on the left side of the screen.

2
Access bookmark properties

Right-click on the bookmark with the incorrect text color (e.g., the blue or gray one) and select 'Properties' from the context menu.

3
Change the appearance color

Navigate to the 'Appearance' tab within the Properties dialog box. Click on the 'Color' option and select your desired uniform color (usually black or dark gray) from the color palette.

4
Apply and repeat

Click 'OK' to apply the changes. Repeat this process for any other mismatched bookmarks in the navigation tree.

Frequently Asked Questions

Why do PDF bookmarks change color after merging?

When you combine multiple PDFs, the resulting document inherits the individual bookmark properties—such as text color, font style, and icon state—from the original source files. If the authors of the original files used different settings, the merged file will display a mismatched appearance.

Can I change the color of all PDF bookmarks at once?

In many advanced PDF editors, you can hold down the Ctrl or Shift key to select multiple bookmarks in the navigation panel, right-click to access their Properties, and change the appearance color for all selected items simultaneously.

What does a blue bookmark icon mean in a PDF?

A blue bookmark icon sometimes indicates that the bookmark contains a special action, such as executing JavaScript, submitting a form, or linking to an external website. Standard gray icons typically indicate a simple navigation link pointing to a page view within the same document.
