The human eye’s discrimination of colours has underscored the work of painters throughout history. Artists instinctively understand that visible light is a complex spectral phenomenon, and the proportion of red, indigo, violet, green and other colour components of white light vary in sunlight. Moreover, the colour of sunlight changes from place to place and from time to time.
Similarly, colour variations also vary widely between different types of artificial light sources, where they can be even more pronounced and have a profound effect on electronic products. Electronic device manufacturers now understand the impact of ambient light colour on the perceived colours from a display and how to dynamically change these colours based on changing scene illuminants.
This article discusses the effectiveness of white-balancing technology and its dramatic impact on both authenticity and accuracy of colours displayed on screen.
