Hi,
Whatever you want to do you would do it inside your page, not on the HTML to PDF converter. For example, you can completely remove that attribute; or put JavaScript code in your page to conditionally set your body's background color as soon as you detect that your page is running inside our converter. See here for more information on how to detect the converter in your JavaScript:

Thanks!
