In the 19th century, mathematician Bernhard Riemann suggested that such spaces might not be flat like a sheet of paper. They might be curved, more like the surface of a globe. Decades later, Erwin Schrodinger applied this idea to colour. He argued that hue (what we call red or blue), saturation (how intense it looks) and lightness (how bright or dark it is) are not random labels. They come directly from the shape of this 3D colour map.
