Device color modes
Dark mode
Dark mode is a device-specific color mode. It affects the colors of interfaces at an operating system level and displays dark grays for most applications.

How it affects UI design
In web applications, dark mode can be given unique styling using the prefers-color-scheme media query.
Dark mode can cause adverse effects for certain users (such as eye strain or migraines) when contrast is too high or if they have light sensitivity.
Colors on a dark background may appear differently than when they are placed on a light background.
The darkness or contrast of colors on a dark background may appear differently than when they are placed on a light background.
