    Unfortunately that is not possible to achieve inside JotForm Builder. Such feature does not exist in JotForm Builder.

    Workaround for this is to add external Java Script to manipulate input fields background. In case of adding external Java Script you will need to get full source code of your form and then to add additional script block to that full source and save that as your web page.  That means that your form need to be embedded to some web page. 

    When you get full source code of your form, then you can add  JS function.

    For more information you can read following article:

    Hope this will help. Let us know if you need further assistance.
