In this book, mathematical, philosophical, and technical considerations unfold regarding the combinatorial colors of color arrangements. Experimental investigations explore the recognition and perception of colors, brightness, and their combinations. Colors and words form strange liaisons: from the polychromy of Roman wall paintings to the grisaille, the camaieu of painted veining in marble, to the uniformity of background and pattern, in the allegory of allegory - as triumph, in play. Here, the ontology of color names in subtle shades meets Helmholtz's color space in the rigid geometry of enthusiasm from Bernhard Riemann to the late Wittgenstein. A stark shift of extremes merges the contrasts and continues into the details of sentence and word arrangement as a mosaic of interchangeably assembled individual parts.
