A camera or colorimeter is said to be colorimetric if it satisfies the Luther condition by Robert Luther (1868–1945) (also called the "Maxwell–Ives criterion"), [5] reducing observer metamerism color errors, if the product of the spectral responsivity of the photoreceptor and the spectral transmittance of the filters is a linear combination ...
The standard observer is characterized by three color matching functions. There is also a 1 nm-interval dataset of CIE 1931 and CIE 1964 provided by Wyszecki 1982. [12] A CIE publication in 1986 appears also to have a 1 nm dataset, probably using the same data. [13] Like the regular 5 nm dataset, this dataset is also derived from interpolation.
Color Space and Its Divisions: Color Order from Antiquity to the present. New York: Wiley. ISBN 978-0-471-32670-0. This book only briefly mentions HSL and HSV, but is a comprehensive description of color order systems through history. Levkowitz, Haim; Herman, Gabor T. (1993).

Color matches made in the paint industry are often aimed at achieving a spectral color match rather than just a tristimulus (metameric) color match under a given spectrum of light. A spectral color match attempts to give two colors the same spectral reflectance characteristic, making them a good metameric match with a low degree of metamerism ...
The above development has the advantage of basing the new X F Y F Z F color matching functions on the physiologically-based LMS cone response functions. In addition, it offers a one-to-one relationship between the LMS chromaticity coordinates and the new X F Y F Z F chromaticity coordinates, which was not the case for the CIE 1931 color ...
The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. [a] It expresses color as three values: L* for perceptual lightness and a* and b* for the four unique colors of human vision: red, green, blue and yellow.

A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or color-matching fans. Typically there are two different types of color charts: Color reference charts are intended
