Color Quality (book chapter)



Yoshihiro Ohno


This book chapter provides the fundamentals of colorimetry and color quality for solid state lighting, including descriptions of the current standards on chromaticity of SSL light sources and color rendering, and recent studies on these topics. Section 8.1 is the general introduction. Section 8.2 introduces the fundamentals of chromaticity, CCT, Duv, and color difference specifications, and in addition, some recent studies on perception of white light chromaticity are introduced. Section 8.3 explains the object color specification, which is important to understand color quality, then Section 8.4 provides the details of the CRI, color preference and perception aspects of color quality, with information on related recent research on color quality. Section 8.6 introduces the definitions of the color-related terms used for single-color LEDs including dominant wavelength, centroid wavelength, and peak wavelength.
