The purple page that is displayed for new tabs in a private window is not affected by themes and/or extensions, nor can it be changed in settings. I am resourcing to this community in hope to find a direction on how can I customize the aforementioned page even if just its colors. Thank you for taking the time to read question.

You can possibly use code in userContent.css to change the background.

@-moz-document url(about:privatebrowsing) {
 /* style rules for the about:privatebrowsing page */
}

DISCLAIMER: modifications made through a userChrome.css or userContent.css file can stop working as Firefox evolves in new releases, and can "break" the interface in serious ways.

WARNING: This script is not provided by Mozilla and is not officially supported Creating a userChrome.css file and other ways of customizing Firefox that are not exposed in the interface are there for developers, not end-users. If it were intended for end-users, you would see a menu option or checkbox; you wouldn't have to hack a text file in a hidden location.

What this means is that even though the functionality you want is no longer supported, a third-party has found a way to do it using the CSS file. If it breaks in new versions, you will need to contact the person who provided the script.
