On Vision and Colors from a prism, however, the production of white can be demonstrated by using a mixture of colored light from each of the three main pairs of complementary colors: red – green, orange – blue, or yellow – violet. White can be produced from two complementary opposite colors when both of the external causes of the colors excite the same retinal place at the same time. Newton claimed that white could be produced by the aggregation of his seven prismatic colors. He erroneously considered color to be in light instead of in the eye. White is the result of the combination
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
