Fix PDF Form Field Colors Reverting in Acrobat on Mac
Question details
The user is unable to retain customized border and background colors for PDF form fields, as the settings revert and become unavailable after the palette is closed.

- Product
- Adobe Acrobat Pro
- Device & OS
- Mac
- Scenario
- Customizing the appearance of interactive form fields within a PDF document.
- Observed behavior
- The form field's border and background colors revert to no color, and the border width or style options become grayed out or unavailable immediately after closing the color palette.
Ensure you have the necessary permissions to edit the PDF document and that the file is not protected by a security password that restricts form modifications.
Set Appearance Properties in Prepare Form Mode
Modify the form field colors properly through the Properties panel in Prepare Form mode, ensuring the field itself is not locked.
In Adobe Acrobat Pro, appearance settings for form elements must be applied specifically to the field properties rather than the general page background. Attempting to change colors outside the dedicated Properties panel or on a locked field can cause the UI to discard your selections.
Open your PDF in Acrobat Pro on your Mac. Go to the 'Tools' menu at the top, scroll down to the 'Forms & Signatures' section, and click on 'Prepare Form'.
Right-click on the specific form field that is losing its color settings and select 'Properties' from the context menu to open the Field Properties dialog box.
Navigate to the 'General' tab within the Properties window. Check the bottom left corner and ensure the 'Locked' checkbox is unchecked. If it is checked, uncheck it so you can make modifications.
Switch to the 'Appearance' tab. Click the color boxes for 'Border Color' and 'Fill Color' to select your desired colors. Adjust the 'Line Thickness' and 'Line Style' dropdowns, then click 'Close' to save the changes.

Verify Document Restrictions and Update Acrobat
If the appearance controls remain unavailable, check the document's security settings and ensure your Acrobat installation is up to date to rule out Mac-specific UI bugs.

Frequently Asked Questions
Why are my PDF form field appearance properties grayed out?
This usually occurs if the PDF document has security restrictions preventing editing, the specific form field has the 'Locked' attribute checked in its General properties, or you are trying to edit the field outside of the 'Prepare Form' mode.
How do I make a PDF form field background transparent?
To make a field transparent, open the field's Properties in Prepare Form mode, navigate to the Appearance tab, click the 'Fill Color' box, and select 'No Color' (usually represented by a white box with a red diagonal line).
Can I change the border color of multiple PDF form fields at once on a Mac?
Yes. While in Prepare Form mode, hold the Command key and click on each field you want to modify to select multiple fields. Right-click any of the selected fields, choose 'Properties', and change the border color under the Appearance tab to apply it to all selected fields simultaneously.
