23‐1: Invited Paper: Visualization of Color‐Gamut Coverage‐Gamut Ring Intersection

Abstract

The D50 CIELAB gamut volume was standardized as a suitable and unified gamut size measurement methodology. The color gamut volume is visualized using proportionate gamut rings in a two‐dimensional diagram. Gamut ring intersection assists the visual comparison of the size and shape of the color gamut coverage between a display and a reference. This paper introduces a desktop application with an intuitive graphical interface for visualizing the gamut rings and describes the algorithm of the gamut ring intersection.

Assessing color capability with gamut ring intersection

“…The GRI diagram 10 is an extension of the original diagram showing the color capability of a test device within the gamut rings of a reference gamut, thereby indicating not only the general coverage of that reference but also where there is good and where there is poor coverage.…”
