default Background Color
The default background color of the web pages loaded in the browser.
This color is used as a default background color when Chromium can't identify the background color. Such may happen if the page is not fully loaded, or the page does not explicitly override the default background.
If a web page is already loaded, its default background color will be updated and an asynchronous request to repaint the web page will be sent.
Initially, the default background color is white.
