THE REAL VERSION OF 'DARK MODE' IN GOOGLE SEARCH
Google has recently released a real version of Dark Mode. Of course, the company had brought the real version of Dark Mode last year. However, in the case of users, it has only recently become available.
Earlier, Google had provided 'grey' background in dark mode. But now it is available in a completely black background.
Google's logo and link will not change even if it is black in the background. This dark mode is still not available to all users.
