How to Fix Acrobat Search Text Appearing Black with a Gray or Green Background

Product: Adobe Acrobat Reader
Device & OS: Android
Scenario: Searching for specific text keywords within a PDF document using a mobile app.
Observed behavior: The highlighted search results display unexpected colors, such as black text on a gray or green background, making the text difficult to read.

Before you start

Ensure your Adobe Acrobat Reader application and Android operating system are updated to the latest versions before troubleshooting display settings.

Solution 1Recommended

Disable Night Mode in Acrobat Reader

Night Mode alters document colors to reduce eye strain, which can invert or change how search text highlights appear.

In the Adobe Acrobat Reader mobile application, search results natively use a green background. When Night Mode is enabled, these colors shift to accommodate dark backgrounds, sometimes resulting in heavy gray or dark green highlights that obscure text.

Open your PDF

Launch the Adobe Acrobat Reader app on your mobile device and open any PDF document.

Access View Settings

Tap the 'View' icon (often represented by a page or glasses icon) in the top menu bar.

Toggle Night Mode

Locate the 'Night Mode' switch and toggle it off to restore standard document colors and search highlighting.

Color Restored: Disabling Night Mode should immediately return your search highlights to the default, legible contrast.

Solution 2

Verify Application Theme Settings

The overall app theme might conflict with search highlighting colors, especially on specific Android devices.

Frequently Asked Questions

Why does my search text highlight look green in Acrobat Reader?

In Adobe Acrobat Reader for mobile, search results are natively designed to appear with black text on a green background. This is the default behavior to make search results stand out.

How do I change the search highlight color in PDF readers?

In most mobile PDF readers, the default search highlight color cannot be customized directly. If the color makes text illegible, disabling Night Mode or switching to a light theme usually restores standard contrast.

What should I do if disabling Night Mode doesn't fix the gray background?

If the issue persists, ensure your application is fully updated. You can also try clearing the app cache by navigating to your Android Settings, selecting Apps, finding Adobe Acrobat, and tapping Clear Cache.
