The "dark-mode" command is a feature or setting that allows you to switch the interface of an application, operating system, or website into a darker color scheme. When you enable dark mode, the background of the user interface changes from the traditional bright or white background to a dark or black background, while the text and other elements can be adjusted to have lighter colors for better visibility.

The purpose of dark mode is to reduce eye strain, especially in low-light environments, and to provide a more visually comfortable experience for users. It can also help conserve battery life on devices with OLED or AMOLED screens since dark pixels require less power.

The implementation of dark mode can vary depending on the platform or application you are using. Some systems have a system-wide dark mode that affects all applications, while others may require you to enable it individually for each specific application or website. It's often found in settings or preferences menus, and can usually be toggled on or off with a simple switch.
