Fusion (Space and Place)

I think when people mean that Discworld books have become darker they really mean the series is growing up. In ‘The Colour of Magic’ most of the city is set alight. It’s a joke, in much the same way that the Earth is destroyed almost at the start of Douglas Adams’s ‘The Hitchhikers Guide to the Galaxy.’
Terry Pratchett

Spectrum/Experimental Colour

One very important difference between color and monochromatic photography is this: in black and white you suggest; in color you state. Much can be implied by suggestion, but statement demands certainty… absolute certainty. – Paul Outerbridge – [Julia Scully, “Seeing pictures”, Modern Photography, Oct. 1976, p. 8]
