If you want to give your walls a dramatic look, try getting a black sky with stars wallpaper. The night sky is typically dark and black, but there are some brighter stars, such as Mars and satur. While earthly skies are largely white, they are often punctuated with asteroid chases. These phenomena may make a star appear dark. These wallpapers are perfect for bold, dramatic home decor and can be downloaded for free on sites like pngtree, where you’ll find more than three million graphics.
