Is is possible to change the colour of the black screen behind the password entry?

Unfortunately, changing the background color of the password-protect form entry is currently not possible. But if you want, we can make a feature request ticket for that, though I may not able to provide an assurance when or will it be implemented.

Please let us know so we could forward a ticket.
