Visualization of reproducible object colors in standard color spaces using the gamut ring intersection

Abstract

Object color coverage by output media is necessary to understand the limitations of color reproduction. However, complex shapes exhibited in 3D color spaces can pose challenges. Even if their 3D plot axes are rotated, their shape and size is generally difficult to understand. In this study, the color gamuts of both real and theoretical objects were selected as reference gamuts and compared with a few standard trichromatic color spaces using gamut rings—a 2D visualization method that allows quantification of color capabilities across lightness, chroma, and hue ranges. Additionally, gamut intersections between the standard color spaces and reference object color gamuts were represented proportionally on the rings to facilitate a straightforward evaluation of the color capabilities of the standard color gamuts.
