Airbus’ new A350 XWB has panels of LEDs that can project 16.7 million shades of color within the cabin, which mimic the hues of the different times of the day.
When travelling east, the plane can expose passengers to brighter lights before dawn, making it seem as if the day has already begun, as it has in their destination. In the reverse direction, continued exposure to light in the evening, can simulate the delayed sunset to the west.
The innovation is said to be a cure for jet lag.
