Darwinian evolution has simplified our color vision to be based on red, green, and blue cones.
Our vision system uses three different sensors (red, green, and blue cones) to selectively detect the visual spectrum,
but colors do not belong to the physicist's official lexicon.
When science is spectral analysis, Art must be light synthesis.
Aposematic symbol art, far from being a passive disguise, such camouflage also involves specific changes in artists and critics behaviour (caution, warning, danger and hazard).
