How to Customize Text and Background Colors in Acrobat Reader Night Mode

Product: Adobe Acrobat Reader
Device & OS: Android
Scenario: Reading PDF documents at night or in low-light environments using a mobile device.
Observed behavior: The default Night Mode enforces a strict black-and-white contrast that cannot be natively customized with specific color codes in the Android app.

Before you start

Ensure your Acrobat Reader app is updated to the latest version. Note that native support for specific hex color customization in the Android app's Night Mode currently requires submitting a feature request to the developers.

Solution 1Recommended

Submit a Feature Request to Adobe

Since Acrobat Reader for Android currently lacks native support for custom hex colors in Night Mode, you can request this feature directly from the development team.

Adobe relies on user feedback to prioritize new features. Submitting a formal request through their Bug Report Form is the most effective way to encourage the addition of customizable Night Mode colors.

Access the feedback form

Open your web browser and navigate to the official Adobe Feature Request and Bug Report Form.

Select your product

Choose 'Adobe Acrobat Reader for Android' from the product drop-down menu.

Detail your request

Fill out the form describing your need for adjustable Night Mode colors. Be specific by mentioning your preferred hex codes, such as a #353535 background with #CCC text, to reduce eye strain.

Submit the form

Click submit so the development team can review your suggestion for future app updates.

Community Support: You can also post this request in the official Adobe Community forums to gather votes from other users experiencing the same eye strain.

Solution 2

Use Android Accessibility Settings for Softer Contrast

As a temporary workaround, you can use your Android device's built-in display settings to soften the harsh contrast of the default Night Mode.

Frequently Asked Questions

Can I use custom hex codes for background colors in Acrobat Reader Android?

Currently, Adobe Acrobat Reader on Android does not support entering custom hex codes (like #353535) for Night Mode backgrounds. Users can only toggle the default high-contrast Night Mode on or off.

Does Acrobat Reader for PC allow custom background colors?

Yes, on the Windows and Mac versions of Adobe Acrobat Reader, you can customize the document colors. Go to Edit > Preferences > Accessibility, check 'Replace Document Colors', select 'Custom Color', and choose your preferred page background and document text colors.

Why is the default Night Mode contrast so harsh?

Acrobat Reader's default Night Mode typically inverts standard colors to pure black and pure white to maximize visibility in dark environments. However, this absolute contrast can cause eye strain for some users, prompting requests for softer gray tones.
