“…This begs the question of why, more than 70 years later, phosphors are still being analyzed using the obsolete NTSC gamut when the potential of new materials is discussed in publications. The phosphors that were used in early color televisions actually established the SMPTE-C color gamut (1968) . Since then, many additional and attainable color gamuts have been developed, such as sRGB/Rec.…”

“…Since then, many additional and attainable color gamuts have been developed, such as sRGB/Rec. 709 (1993), Adobe RGB (1998), and DCI-P3 (2008) color gamuts. , Most of these gamuts are used in commercial devices such as 4K UHD televisions and high-end digital cameras . The next-generation color gamut is the notably large ITU-R color space recommendation BT.…”

In the race to develop new luminescent materials for the next generation of light-emitting-diode (LED)-based solid-state lighting and display applications, it is often forgotten that color theory and human perception should be some of the principal factors guiding materials design. In this Viewpoint, we explore some of the antiquated colorimetrics established originally for incandescent and fluorescent lighting and discuss how they are still widely applied in the literature today to interpret the color quality of luminescent materials, like inorganic phosphors and quantum dots, and to analyze prototype devices, despite their shortcomings. We then shift our analysis toward contemporary ideas in color theory that more accurately describe the color quality of modern LED light bulbs and flat-panel displays. Finally, the perspective examines the opportunities and challenges of applying these new concepts to guide the design of luminescent materials used in LED-based applications.

“…Figure 4 shows the comparison of gamut shape in CIELAB space. It is visualized with the gamut expanded especially in bright orange, cyan, dark red, and dark purple regions in the six-primary-color display 19,20 (see also "The NTSC Color Triangle Is Obsolete, But No One Seems to Know" in the May 2006 issue of Information Display. )…”
