Seeing, adapting to, and reproducing the appearance of nature

Mark D. Fairchild
2014 Applied Optics  
The perception of color in nature is a complex multidimensional phenomenon.  ...  The color experience is reduced to the appearance attributes of brightness, lightness, colorfulness, chroma, saturation, and hue from spectral energy distributions in the scene, while the vast range of  ...  Ultimately, all these mechanisms of color perception reduce the spectral stimulus array to six perceptual dimensions of color appearance.  ...
