- Product
- PDF Reader / Editor
- Device & OS
- not provided
- Scenario
- Using custom JavaScript validation to conditionally change the background color of a PDF date field.
- Observed behavior
- The custom red fill color is replaced or disappears when the form field becomes inactive or loses focus on different computers.
Before troubleshooting, ensure all users are opening the PDF in a fully-featured PDF application that supports interactive form fields and custom JavaScript execution.
Turn Off Form Field Highlighting
Field highlighting can override custom fill colors when the field is inactive. Disabling this feature resolves the display issue.
Many PDF readers apply a default background highlight to make fillable forms easier to identify. When a field loses focus, this default highlight is applied over your custom validation color, making it seem like the color has reset or disappeared.
Launch your PDF reader (such as Adobe Acrobat) and open the document. Go to the Edit menu and select 'Preferences'.
In the Preferences dialog box, locate and click on the 'Forms' category from the left-hand sidebar.
Find the 'Highlight Color' section and uncheck the option for 'Show border hover color for fields' or turn off 'Fields Highlighting'. Click 'OK' to save.
Check Script Placement and Field Properties
Ensure the JavaScript validation code is attached to the correct event and that field properties are consistently formatted to prevent script failures on different devices.

Frequently Asked Questions
Why does my PDF form field color change when I click away?
By default, many PDF viewers use a light blue or custom highlight color to make interactive fields easily visible. When a field loses focus, this default highlight color overlays or replaces your custom background color.
Will disabling field highlighting affect other users?
Yes, field highlighting is an application-level setting on the user's computer. You cannot turn it off globally for everyone via the document itself. You may need to instruct users to adjust their local viewer preferences if they experience this issue.
How can I ensure my PDF date format stays consistent across different computers?
You can enforce date consistency by setting a predefined date format (e.g., dd/mm/yyyy) in the field's properties under the 'Format' tab before saving and distributing the form.
