The Gamut Obtainable with Surface Colors

The gamut obtainable with surface colors has been investigated 20 years ago by Michael R. Pointer [1]. Since then, new coloring and imaging techniques have allowed to generate surface colors with higher chroma values than Pointer has found. Color gamut inspections are elaborated by means of convex hull examinations which allow to quantify the gamut volume. If this calculation is made in a perceptually uniform color space as for instance Munsell, the number of discernible colors may be derived from the calculated volume. In this study, the volume of the gamut obtainable with surface colors is compared with the gamut of optimal colors (representing the theoretical limits of all object and non-fluorescent self-luminous colors). In that context it is further discussed how many colors the eye can distinguish - a question which is 100 years old but is conceived to be clarified on the basis of new calculations.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
