AbstractThe concept of the gamut of a colour reproduction system is explained, starting from the spectrophotometric description of colorants used. The extension is made from spectrophotometry to C1E 1931 XYZ colorimetry, a system still in use for the description of colour gamuts. Advantages of the CIE 1976 u’,v’ uniform chromaticity chart are discussed

Additive colour properties and colour gamut of cholesteric liquid crystals
Nature, 1978LIQUID crystals are organic compounds in a state of matter intermediate between the isotropic liquid and crystaline solid. They are fluid but at the same time they exhibit molecular order. Depending on the ordering one distinguishes the smectic, the nematic and the cholesteric liquid crystals1 (CLC).

Colour gamut size and shape influence colour preference
Lighting Research & Technology, 2016Two psychophysical experiments were conducted to investigate the effect of colour gamut size and shape on colour preference. In the first, two side-by-side booths were designed to resemble a retail setting with clothing; in the second, a single booth was designed to resemble a restaurant setting, but also included a mirror to permit the observer's ...

Colour discrimination scores combining colour fidelity and gamut area characteristics
Lighting Research & Technology, 2022This paper investigated colour discrimination based on current available indexes, and predictors were proposed for global and targeted colour scenarios. Thirty participants conducted the Farnsworth–Munsell 100 hue test under 21 lighting conditions. The experiment results revealed that the distribution of total error score (TES) and

The Gamut of Real Surface Colours
Color Research & Application, 1980AbstractA maximum gamut for real surface colours has been derived from the analysis of the colour coordinates of 4089 samples. The gamut has been derived in both the CIE 1976 L* u* v* colour space and the CIE 1976 L* a* b* colour space. The data are compared with the gamut produced by a typical dye set used in a photographic colour paper, and with the ...

False-colour palette generation using a reference colour gamut
SPIE Proceedings, 2015Monochrome images are often converted to false-colour images, in which arbitrary colours are assigned to regions of the image to aid recognition of features within the image. Criteria for selection of colour palettes vary according to the application, but may include distinctiveness, extensibility, consistency, preference, meaningfulness and ...
