City lights may appear bright to our eyes, but the reality is that their different sources (fluorescent, halogen, sodium, tungsten, neon) provide varying levels of intensity as well as colour cast.

With a digital camera's white balance control, photographers can digitally compensate for the colour temperature, so that the colours in an image appear more natural.
