Interesting thread! A few things I like to contribute: * No machine can fully compete with the AWB in our brains. A person sitting under a green sunshade might get a greenish skin colour, our brain knows about this effect and corrects for it. The greenish skin colour might remain un noticed by us. But looking to the picture later we see a greenish face! The question is : what do we want in our photographes? Reallity (in the above example greenish skin colour) or natural looking colours? I always go for the last one meaning I have to correct in post processing. * I remember the principle way of working of the lamps discussed: discharges in noble gas emit UV, the UV hits special phosphor on the glass, the phosphor emits visible light, to get white light a mix of different phosphor is used, those different phosphors emit different colours. In an old fashioned (non-electronic ballast) the phosphor is excited at the mains frequency (50 or 60 times per second) It is almost certain that the different phosphors for the different colours do not decade their intensenty in the same timing. So over a period of 1/50 second the colour might be white, but if I take a picture with a faster shutter time, the colour will depend on the excact portion of the 1/50 second that I hit.
