Users are experiencing an issue where PDFs look like inverted color negatives when opened in the mobile app.

How to Fix Colors Inverting in Acrobat Reader Mobile on iOS

Product: Adobe Acrobat Reader Mobile
Device & OS: iOS
Scenario: Opening and reading imported PDF documents in the mobile app, particularly after enabling Liquid Mode or system theme changes.
Observed behavior: PDF pages display as inverted negatives despite iOS accessibility color inversion settings being disabled. This occurs because the app automatically inherits the system's dark theme.

Before you start

Check if your iPhone or iPad is currently set to Dark Mode, as recent app updates force the PDF viewer to synchronize with your system-wide appearance settings.

Switch Your iOS Device to Light Mode

Since Acrobat Reader Mobile automatically follows your device's display theme, switching your iOS system back to Light Mode will restore the original colors of your PDFs.

Recent updates to Acrobat Reader Mobile introduced automatic system theme integration. This means if your iOS device is utilizing Dark Mode, the app attempts to adapt the PDF by generating a dark background, which often inadvertently creates an inverted or negative image effect on your documents.

Open the iOS Control Center

Swipe down from the top-right corner of your screen (or swipe up from the bottom edge on devices with a Home button) to access the Control Center.

Disable Dark Mode

Tap and hold the brightness slider, then tap the 'Dark Mode' icon at the bottom to switch your device back to Light appearance.

Use the Settings App (Alternative Method)

Navigate to your iOS 'Settings' app, select 'Display & Brightness', and tap the 'Light' option under the Appearance section.

Restart Acrobat Reader

Swipe up from the bottom of your screen to open the app switcher, swipe away Acrobat Reader to close it completely, and reopen your PDF to view it in its intended colors.

Immediate Resolution: Once the system theme is switched to Light Mode, Acrobat Reader will instantly stop inverting the colors of your imported documents.

Frequently Asked Questions

Why does Acrobat Reader Mobile invert colors when my iPhone is in Dark Mode?

Recent feature updates integrated the application's reading view tightly with the iOS system theme. When the system detects Dark Mode, the app applies a dark overlay or inverts colors to match, which often results in PDFs looking like negative images.

Can I disable the theme sync in Acrobat Reader without changing my iOS settings?

Currently, Acrobat Reader Mobile natively forces the app theme to follow the iOS system theme. There is no isolated toggle within the app to disable this behavior, meaning you must switch iOS to Light Mode to restore normal colors, or use an alternative reader like WPS Office.

Did enabling Liquid Mode cause my colors to invert?

While many users first notice the issue after tapping Liquid Mode, the color inversion is actually controlled by your device's Dark Mode setting. Liquid Mode reformats text for mobile screens but relies on the app's inherited theme colors to render the background.
