“…Most existing metrics used to quantify observer metamerism 13‐20 are proposed based on three‐ and four‐primary‐based displays or projectors. Combination RGI (red, green, indigo) of the constructed system is the primary combination most similar to typical LCD/LED displays: the chromaticity coordinates of R is (0.69, 0.31), which is very close to sRGB red (0.64, 0.33); and the G (0.22, 0.71) is almost exactly the AdobeRGB green (0.21, 0.71); the I (0.15, 0.05) is almost exactly the blue of sRGB (0.15, 0.06).…”

In this article, a dual seven‐primary lighting system is constructed for color research and education. The system offers sufficient spectral variability to approximate the spectral power distribution of a variety of standard illuminants. More importantly, the constructed multiprimary lighting system was verified to have crucial advantages over conventional displays/projectors to probe observer metamerism through the generation of individualized metameric color stimuli. An observer metamerism index to describe the potential for observer metamerism of any generated stimulus pairs with respect to the population variation of color‐normal observers is formulated. The metric is further extended for use in quantifying the potential for observer metamerism of any lighting system or a system‐primary combination. Moreover, 10 pairs of lighting stimuli, customized for exhibiting high degrees of observer variability, were produced using the system as a step toward creating a device for the color matching functions characterization of individual observers, a so‐called observer calibrator.

Color matching experiments were conducted for 11 pairs of displays, using 7 displays with different spectral characteristics. The color matching results between the LCD display and displays that have a narrowband spectrum, such as a laser projector, QLED, or OLED, demonstrated a significant color difference between two matched colors. The maximum difference was 18.52 ΔE00, which indicates the white color difference between the LCD and laser projector. There was also a clear observer variability of 2.27 ΔE00. The new cone fundamental function derived from 757 metameric pairs showed good performance compared to CIE standard observers reducing the display color mismatching significantly. This function also demonstrated a better performance when evaluating color matching in color chart image.
