On Vision and Colors tried to demonstrate physiologically that color is "specially modified activity of the retina." The initial basis for Schopenhauer's color theory comes from Goethe's chapter on physiological colors, which discusses three principal pairs of contrasting colors: red/green, orange/blue, and yellow/violet. This is in contrast to the customary emphasis on Newton's seven colors of the Newtonian spectrum. In accordance with Aristotle, Schopenhauer considered that colors arise by the mixture of shadowy, cloudy darkness with light. With white and black at each extreme of the scale, colors are arranged in a series according to the mathematical ratio between the proportions of light and
Inverted spectrum of the simulation can be separated from the code that determines "in which colors" the simulation is displayed by the headset (as well as determining "which perspective" in the simulation to display). So, it would be possible to change that additional code, inverting the displayed colors, without changing anything about the simulated physics. Hence, which (real-world) colors are displayed is a further fact over and above the facts of the simulated physics. In his book "I Am A Strange Loop", Douglas Hofstadter argues that the inverted spectrum argument entails a form of solipsism in which people can have no idea
