The capacity to invert the standard light-on-dark color scheme of a reading application on Kindle devices and platforms is a user interface option. This feature presents light-colored text against a dark background, altering the visual presentation of digital books and documents. An example of this configuration is viewing white text on a black screen within the Kindle application.
This alternative display method offers several advantages. It can reduce eye strain, particularly in low-light environments, by minimizing the contrast between the screen and surroundings. Further, it potentially conserves battery power on devices with OLED or AMOLED screens, as fewer pixels are illuminated. Functionality of this type has become increasingly prevalent across various applications and operating systems, reflecting a growing awareness of digital well-being and user comfort.
