How do you change the color of a text field after text is entered in it?

I am creating a form with multiple text fields. Once a field is filled in, I would like the text field to change colors. I am having no luck getting that to happen. I've tried multiple ways. Any ideas on how to accomplish this? Thanks!

As the custom calculation script of your field enter the following:

event.target.fillColor = (event.value==event.target.defaultValue) ? color.transparent : color.blue;

You didn't specify which colors you want to use, so I assumed transparent for the empty fields and blue for the filled-in ones...

You can also use the Validation event (with the same code) if your fields already have a calculated value.

Thanks! They are currently clear and would want them to be blue. The fields would be a custom text field. That's the problem I am running into. I've tried different custom scripts but couldn't seem to get it correct. Coding isn't my thing 🙂
