Color predictions that incorporate light scattering effects of pigment particles and paint layer thickness require approaches based on the Kubelka—Munk [19] equations.

Even such approaches cannot predict the color of paint mixtures precisely since small variances in particle size distribution, impurity concentrations etc. Artists typically rely on mixing experience and "recipes" [20] to mix desired colors from a small initial set of primaries and do not use mathematical modelling.

There are hundreds of commercially available pigments for visual artists to use and mix in various media such as oil, watercolor, acrylic, gouache, and pastel. A common approach is to use just a limited palette of primary pigments [21] often between four and eight that can be physically mixed to any color that the artist desires in the final work.

There is no specific set of pigments that are primary colors, the choice of pigments depends entirely on the artist's subjective preference of subject and style of art as well as material considerations like lightfastness and mixing heuristics. Contemporary classical realists have often advocated that a limited palette of white, red, yellow, and black pigment often described as the "Zorn palette" is sufficient for compelling work.

The human eye normally contains only three types of color photoreceptors, known as long-wavelength L , medium-wavelength M , and short-wavelength S cone cells.

These photoreceptor types respond to different degrees across the visible electromagnetic spectrum. The LMS primaries are complete since every visible color can be mapped to a triplet specifying the coordinates in LMS color space. Normalized cone spectral sensitivity curves The L, M and S response curves cone fundamentals were deduced from color matching functions obtained from controlled color matching experiments e.

The X, Y, and Z primaries are typically more useful since luminance Y is specified separately from a color's chromaticity. Any color space primaries which can be mapped to physiologically relevant LMS primaries by a linear transformation are necessarily either imaginary or incomplete or both.

The color-matching context is always three dimensional since LMS space is three dimensional but more general color appearance models like CIECAM02 describe color in six dimensions and can be used to predict how colors appear under different viewing conditions.

Thus for trichromats like humans, we use three or more primaries for most general purposes. Adding a reasonable choice of the third primary can drastically increase the available gamut, while adding a fourth or fifth may increase the gamut but typically not by as much.

Most placental mammals other than primates have only two types of color photoreceptor and are, therefore dichromats , so it is possible that certain combinations of just two primaries might cover some significant gamut relative to the range of their color perception. Meanwhile, birds and marsupials have four color photoreceptors in their eyes, and hence are tetrachromats. There is one scholarly report of a functional human tetrachromat.

Measuring functional spectral discrimination in non-human animals is challenging due to the difficulty in performing psychophysical experiments on creatures with limited behavioral repertoires who cannot respond using language.

Limitations in the discriminative ability of shrimp having twelve distinct color photoreceptors have demonstrated that having more cell types in itself need not always correlate with better functional color vision. Main article: Opponent process The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from cones and rods in an antagonistic manner.

The theory states that every color can be described as a mix along the three axes of red vs. The six colors from the pairs might be called "psychological primary colors" because any other color could be described in terms of some combination of these pairs.Beginning with a survey of underappreciated masters who perfected the use of color and light, the book examines how light reveals form, the properties of color and pigments, and the wide variety of atmospheric effects.

James Gurney at least stays away from weird mythical art mumbo-jumbo, as he actually has a formal scientific background archeologist.

In general, we cannot completely predict all possible perceived colors from combinations of primary lights in the context of real-world images and viewing conditions. Nonetheless, Gurney's attention to detail shines through and he at least alerts you to the existence of very subtle phenomena like that the difference in atmospheric density at high altitude IS artistically relevant.
