The photo is of a small area, about half A4, of polished blue marble in the Cairns Marble show room in Australia. I have enhanced the colour and contrast slightly to emphasize the crystal structure, but the marble really is blue, though slightly greyer, lighter, and less contrasty than the photo. It looks three dimensional but it really is a flat polished surface.
