How to Manage Color Loss in PDF Night Mode on Mobile
Question details
Users want to preserve the visibility and contrast of colored text when using night mode in a mobile PDF reader.
- Product
- Mobile PDF Viewer
- Device & OS
- not provided
- Scenario
- Reading PDFs containing color-emphasized text (such as red font) in dark environments using the app's built-in night mode.
- Observed behavior
- Colored text loses its contrast and appears gray, significantly reducing readability compared to viewing the document in standard mode.
Check your smartphone's built-in accessibility settings, as system-level color inversion features might offer better contrast for colored text in PDFs than the app's default night mode.
Submit a Feature Request for Advanced Color Filtering
Since specific color preservation is not natively supported in the app's current night mode, submitting a formal feature request ensures the product team evaluates the need for an advanced color-filtering update.
The current PDF night mode applies a uniform darkening filter that inadvertently neutralizes highlighted or colored text. User feedback is directly monitored by developers to prioritize quality-of-life updates.
Launch the mobile app and navigate to the 'Me' or 'Profile' tab located at the bottom right of the screen.
Tap on 'Help & Feedback' or the 'Feedback' button from the menu list.
Select 'Feature Request' or 'Bug Report'. Describe the color contrast issue in PDF night mode, specifically mentioning the desire for a Smart Invert-style color filter, and tap 'Submit'.
Use Device-Level Smart Invert (iOS/Android Workaround)
Leverage your smartphone's native accessibility settings to intelligently invert screen colors, which often preserves document colors better than basic dark modes.

Frequently Asked Questions
Why does colored text look gray in PDF night mode?
Standard app-level night modes often apply a uniform dark overlay or directly invert black and white elements to reduce screen glare. This process can inadvertently neutralize color saturation, causing red or other bright text to appear washed out or gray.
Can I use iPhone's Smart Invert while reading PDFs?
Yes. While the app has its own built-in Night Mode, you can disable it and instead use iOS's system-level Smart Invert feature (found in Settings > Accessibility > Display & Text Size) to selectively darken the screen while better preserving image and text colors.
Will advanced color filtering be added to the mobile PDF reader?
The product development team actively reviews user feature requests. Submitting your feedback regarding color loss during night mode helps prioritize the integration of advanced color filtering in future updates.
