“…A similar disappearance of red and blue-or in other words, the appearance of brightening-has, as far as is known, not been pursued. Duck (1987;2016) examines the disappearance of yellow and cyan-he refers to cyan as blue-and utilizes a specific effect: that of the change in hue due to reduction in brightness, leading to the extinction of yellow and cyan (the Bezold-Brücke effect). Not only does this approach mistake the relation between intensity of vision-as critiqued by Kidder (1989), Matthaei (1932), Currie (2010)-and its reduction in relation to colour overlaps, but the clear presence of yellow and cyan in the inverse spectrum even under dim conditions, which plainly contradicts the Bezold-Brücke effect, is not even addressed.…”

The polarity of light and dark in the treatment of the Newtonian spectrum and the inverse spectrum is studied further and the validity of heterogeneity of light and darkness in relation to Goethe's views is examined. In order to clarify the reality of the "darkness rays", the experimentum crucis is re-evaluated. It is shown that the commonly accepted analysis contains assumptions in the choice of the spectrum and background, which mask the inherent dynamic of the spectrum. The relation between colour and wavelength is reexamined with respect to the immutability and specific refrangibility of colour. It is then shown that both these properties are approximations that apply under the specific conditions that have later become standardized in spectroscopy, leading to a consensus regarding the relation of wavelength to colours of one particular spectrum. This consensus has resulted in the study of colour diverging into spectroscopy and colour physiology. As an alternative, the basis of the dichotomy postulated by Müller is studied, leading to the realization that the resolution of this dichotomy was begun by Goethe with the idea of turbidity. A further study shows that turbidity resolves the apparent incompatibility of light and dark.
