ACM SIGGRAPH Computer Graphics, 1978
Digital control of color television monitors—in particular, via frame buffers—has added precise control of a large subset of human colorspace to the capabilities of computer graphics. This subset is the gamut of colors spanned by the red, green, and blue (RGB) electron guns exciting their respective phosphors.

Overview of Color Gamut Scalability
IEEE Transactions on Circuits and Systems for Video Technology, 2017Displays’ new rendering capabilities combined with the ever-growing number of video applications have fueled the emergence of new video formats addressing wider color gamut and larger frame size. Thus, the need in scalable compression technology to provide backward compatibility with legacy devices and capitalize on the superior compression performance

Journal of the Society for Information Display, 2004
Abstract— This paper describes the architecture for a color picture tube (CPT), which enables a cost‐effective expansion of the color gamut. Besides a gamut expansion based on application of more‐saturated phosphors in the present three‐primary system, four‐ and five‐primary systems are described.

Color Gamut Scalable Video Coding
2013 Data Compression Conference, 2013This paper describes a scalable extension of the High Efficiency Video Coding (HEVC) standard that supports different color gamuts in an enhancement and base layer. Here, the emphasis is on scenarios with BT.2020 color gamut in an enhancement layer and BT.709 color gamut in the base layer.

Color difference evaluation for wide-color-gamut displays
Journal of the Optical Society of America A, 2020With the emerging demand for wide-color-gamut displays, an issue has been raised in which the commonly used color difference formulae or uniform color spaces that were derived based on the data produced in the relatively smaller color gamut could be unreliable for predicting color differences in the highly saturated color regions.

Color gamuts in dim illumination
SPIE Proceedings, 2008Rods act as color receptors in dim illumination. Several recent studies have measured the range of colors at low-light levels in different illuminants. This paper reviews these results and adds new experiments using long-wave-rich illumination, appropriate for rod and long-wave cone interactions.

A Gamut Preserving Color Image Quantization
14th International Conference of Image Analysis and Processing - Workshops (ICIAPW 2007), 2007We propose a new approach for color image quantization which preserves the shape of the color gamut of the studied image. Quantization consists to find a set of color representative of the color distribution of the image. We are looking here for an optimal LUT (look up table) which contains information on the image's gamut and on the color distribution

Improving gamut mapping color constancy
IEEE Transactions on Image Processing, 2000The color constancy problem, that is, estimating the color of the scene illuminant from a set of image data recorded under an unknown light, is an important problem in computer vision and digital photography. The gamut mapping approach to color constancy is, to date, one of the most successful solutions to this problem.
