- Scenario

Frequently Asked Questions
Why do PDF form fields appear purple by default?
Adobe Acrobat highlights interactive form fields in light purple by default to act as a visual aid. This helps users quickly identify where they need to click and type when filling out a digital document.
Will the purple highlight print on the final document?
No, the purple field highlighting is purely an on-screen visual guide. It will not appear when the document is printed or when the form is flattened and saved.
How do I make a PDF form field completely transparent?
To make a field transparent, open the form in editing mode, right-click the specific text field, select 'Properties', go to the 'Appearance' tab, and set both the 'Border Color' and 'Fill Color' to 'No Color'.
Can I change the highlight color instead of removing it?
Yes. You can change the highlight color by going to 'Edit' > 'Preferences' > 'Forms' in Adobe Acrobat, and selecting a new color from the 'Fields highlight color' palette to better match your document's design.
