Indeed. I would have imagined something like the images on the second of those
two links, based on what little I have read on the subject - mainly
well-researched fiction, it has to be said. And I don't watch (or even
receive!) CNN, so I couldn't comment on the 'creative' nature of their
broadcast images.

It's easy to see how colours are recorded and perceived differently - try taking
pictures with any digital camera of an indoor scene, no flash, with the
different colour temperature settings. They all match up with what your mind
sees to some degree, but the difference in the colours is startling.

I should add that I am well aware of the unrealistic nature of my lego render -
my intention was a bright, garish hollywood background to fit with the
primary-colour nature of the lego sets!
