When it is stimulated the chromatophore produces black, red, brown and yellow colors (Mäthger et al. 2005).

Kepler uses this argument to show that society should not always trust its observations and that even though there is no observed feelings of wind or vibrations, society should not claim that this absence of observed phenomenon supports their interpretation of the Bible that there is a geocentric universe.
