Apps must adapt for nighttime driving where bright screens can be distracting.
The experience must adapt to different lighting conditions to avoid poor readability or glare. In low-light environments, this means reducing the brightness of the screens. Content shown during the daytime can be positive (dark text on light background) or negative (light text on dark background), while nighttime content must be negative. Set the Android Auto per-app system colors specifically for day and night to optimize for maximum readability.
