Light-on-dark color scheme,also called black mode,dark mode,dark theme or night mode,is a color scheme that uses light-colored text,icons,and graphical user interface elements on a dark background and is often discussed in terms of computer user interface design and web design.

Displays with reduced blue light may improve sleep quality
