66‐4: Evaluation of Display Color Chromaticity Gamut Efficiency Based on Real Objects Colors

This paper introduces a simple metric for Color Chromaticity Gamut Efficiency (G.E) in terms of color chromaticity in nature. Color Chromaticity Gamut Efficiency is defined as how efficiently a display covers the chromaticity of real objects in nature such as the Standard Object Color Spectra (SOCS) and Pointer's. G.E can be calculated by reproducible area, non‐reproducible area and non‐efficient area regarding real object colors. G.E is higher when the display's color gamut covers ROC efficiently and accurately. Our study found that Adobe + Display P3 has the best color gamut in terms of G.E among various standards including BT.2020. G.E can serve as a guideline for manufacturers when designing display parameters. For instance, a manufacturer might choose to reduce power consumption instead of expanding the color gamut considering G.E. It is expected that consumers could choose a better display with an efficient color gamut, G.E.
