The feature that inverts the display of an application on Apple’s mobile operating system, displaying light text on a dark background, is a system-wide appearance setting. For example, within the native Mail application, the white background traditionally found behind email content transforms to black, while the black text becomes white.
This adaptation offers several advantages, including potential reduction in eye strain, especially in low-light environments. Further, the shift in color schemes can contribute to power conservation on devices with OLED screens, where black pixels consume less energy. The introduction of this display option marked a significant user experience enhancement, aligning with growing preferences for personalized and adaptable interfaces.
