Fillable Field color change with text

[defaulthqvxlsphzfjs]

Is there a way you can create a fillable PDF with text field properties that have a color border that will go away when the user has filled in the box?

Sure. As the custom Validation script of the field, enter the following:

event.target.lineWidth = (event.value=="") ? 0 : 1;

You'll need to set the border color beforehand, though, for it to work.
