Adjusting the Amazon application’s visual theme to a darker palette modifies the interface’s color scheme, replacing bright backgrounds with darker hues. For example, instead of a white or light gray backdrop, the app displays a black or dark gray screen with light-colored text.
Implementing this alteration can reduce eye strain, particularly in low-light environments, and potentially conserve battery power on devices with OLED or AMOLED screens. Historically, darker interfaces were initially implemented to save power on older CRT monitors, but today, they primarily address user comfort and aesthetic preferences.
