On formal concepts of color-inverted Earth

Abstract

This paper deals with the problem of color inversion, in the form of the intra-personal inversion. Its main goal is to show that there is something mathematically wrong with any concept of color-inverted Earth. Two such concepts (according to two different ways of conceiving color-inversion) are formally sketched and investigated. An intuitive example is produced in order to show that color-inversion is not distributive to color composition, this mathematical property of inversion being the main assumption of any scenario of intra-personal spectral inversion conceivable.
