Tower of Babel I: two processings
An illustration of The Blue Hour and the effect of ozone absorption in the atmosphere after sunset. The upper image is processed with a 'daylight' white balance setting while the lower image uses an 'as-shot' auto white balance.
The upper image has a 'real' blue colour cast but the human visual system in the outdoors compensates much as the digital camera computes its auto balance.
The colour temperature of the ambient illumination in twilight can reach 15,000K.
