The system-wide visual setting in Apple’s mobile operating system inverts the color scheme, rendering light elements dark and dark elements light. This adjustment primarily affects the user interface and supported applications. For example, a predominantly white screen with black text transforms into a black screen with white text.
This visual mode offers several advantages, including potential reduction in eye strain, especially in low-light environments. Furthermore, it may contribute to energy conservation on devices with OLED displays, as darker pixels consume less power. Its introduction marked a significant step toward providing users with greater control over their visual experience and addressing accessibility concerns.
