1. Introduction
Throughout the first third of the 20th century, a key feature of the Russian avant-garde was innovative experimentation with color (see e.g.,
Barron and Tuchman 1980;
Kampasakali et al. 2007;
Ioffe and White 2012;
Bowlt 2017). The most intensive research on color was conducted at the State Institute of Artistic Culture (GINKhUK) under the initiative and guidance of Mikhail Matyushin (1861–1934), a charismatic personality who entered the history of the arts as a painter, composer, art, and music critic, teacher, and experimental researcher in the psychophysiology of art perception. In 1924, Matyushin was appointed in GINKhUK to direct the Department of Organic Culture (
Gamwell 2002). Under his expert guidance, Matyushin’s disciples formed two different working groups,
Zorved and
KORN (see e.g.,
Zhadova 2007;
Cannon 2009).
The group Zorved, whose name combined zorkost (acute vision) and vedaniye (knowledge), was created in April 1923 to study the relationship between color, shape, and sound. Regular members of this group included Nikolay Greenberg and the following four talented Ender siblings: Boris, Georgy, Maria, and Xenia.
The other group, KORN, whose name originated as an acronym for Koллeктив pacшиpeннoгo нaблюдeния (Kollektiv rasshirennogo nablyudeniya), or Collective of Expanded Observation, included Elizaveta Astafieva, Vera Besperstova, Irina Walter, Olga Vaulina, Valida Delacroix, Nikolai Kostrov, Evgenia Magaril, and Elena Khmelevskaya.
In the GINKhUK laboratory, Matyushin and his disciples conducted numerous psychophysiological experiments with color, focusing on changes in colored objects’ chromatic characteristics under the influence of various factors in their spatial environment. The researchers studied how motion, angles of view, and shape affect chromatic characteristics (see for more details:
Kapelush 1976;
Povelikhina 1975/76,
1999a;
Nesmelov 2007;
Tillberg 2002,
2003,
2013;
Matyushin 2011;
Wünsche 2012).
Most of these experiments were organized in real space with large objects. For example, a 6 × 6 m color screen and a 60 cm diameter swinging circle facilitated the study of motion’s impact on color change patterns. A colored pendulum was set in motion with an oscillation amplitude of 5 m. The experimenters observed the pendulum’s color in the following different ways: first by concentrating their eyes on the moving circle, then by focusing on the background screen. Observations of shifts in color perception were carefully recorded. The experiment was repeated over and over again, incorporating different colors for the pendulum and screen (see for more details:
Nesmelov 2007, pp. 23–24).
To analyze changes in color perception depending on the angle of view, painted circles were suspended in different positions relative to the observer as follows: directly at eye level at a distance of 4–5 m, or on both sides of the head at a distance of 2 or 6 m from each other. The researchers studied how the position of the object affected the perceptual characteristics of color and how these sensations changed over time (
Nesmelov 2007, pp. 23, 25).
Constant observations of color changes in nature and their experimental testing in the GINKhUK laboratory led Matyushin to a number of conclusions about some general patterns governing color variability. In particular, the researchers inferred that color plays an important form-building role as follows: warm colors “soften” sharp forms, whereas cold colors, on the contrary, can sharpen rounded edges. Color changes correlate with expansions in the angle of view, as well as with the dynamics of motion. Most importantly, the researchers became convinced that between a colored object and the surrounding environment a third, linking color always appears.
The main outcome of the experimental research by Matyushin and members of the groups
Zorved and
KORN was the treatise
A Reference Book of Color: The Laws Governing the Variability of Color Combinations, first published in Leningrad in 1932 and republished in 2007 (
Matyushin [1932] 2007). The book addressed the practical use of color in interior and exterior architectural design, textile, porcelain, wallpaper, printing, and other industries, and consisted of four sections with color charts, as well as a large article entitled “The Law of the Variability of Color Combinations.” In this article, Matyushin attempted for the first time to introduce the ideas that later formed the basis of his color theory. The key idea concerned the relativity of colors in their interaction in combinations. Matyushin viewed color as a complex, fluid phenomenon, dependent on variables such as neighboring colors, the strength of illumination, and the scale of color fields. He made an appeal for considering color as possessing dynamic visual properties in space and time.
One of color theory’s main concepts relates to “expanded vision” (see, e.g.,
Povelikhina 1999a, p. 49). Matyushin used this term to denote the ability to see not only details but also to encompass everything observed at once and in its entirety. He was convinced that a person’s ability to “widen the angle of vision” could gradually develop as a habit of “seeing everything at once, fully and all around oneself,” bolstered by special exercises similar to conventional gymnastics. He even claimed that by using all possible channels of perception, one can “learn to see with the back of the head, the parietal lobe, the temples and even the soles of the feet, just as Yoga in Hinduism teaches us to breathe not only with the lungs but with all parts of the body” (
Matyushin 1976, pp. 185–86).
As scholars of Matyushin’s life and work rightly observe, his work
Movement in Space, painted in 1921 (
Figure 1), can be seen as a kind of epigraph to the
Reference Book of Color. Like the book, the large canvas embodies an inquiry into the interaction of color and the environment. The canvas represents the intrinsic aesthetic significance of color by means of forcefully extended diagonal multicolored lines, rendered with carefully chosen variations of lightness and chroma of red, orange, yellow, yellow-green, blue, light blue, and purple. The artist demonstrates that color in art has an “independent life and movement” (
Matyushin 1915/16, p. 5), as well as that color perception is not static but kinetic and fast-paced, depending on space, environment, and time. The painting inevitably leaves the viewer with a sense of each color being influenced by neighboring colors, their size, and their location (
Cannon 2009, pp. 71–72). Moreover, this perception varies depending on the degree of illumination and the angle of view as follows: colors are perceived differently depending on whether the viewer uses central, “expanded,” or peripheral vision (
Matyushin 1976).
The authors considered the
Reference Book of Color “a first step in determining the regularity of color relations” (
Matyushin [1932] 2007, p. 15). They saw the book as primarily aiming to establish the “connection between the conceptual color in science and the material color in practice” (
Matyushin [1932] 2007, p. 28). Conclusions about color variability presented in the
Reference Book stemmed naturally from Matyushin’s and his disciples’ art education, from their experience of using color in artistic practice, and, most importantly, from many years of everyday observations of color variability in both laboratory conditions and natural environments. The development of Matyushin’s color theory remained incomplete. However, his understanding of color abounds with original and innovative ideas that have not lost their relevance to this day. Matyushin’s theory represents an important point in the history of color design and undoubtedly deserves serious attention and detailed research.
Several authors have carefully studied the
Reference Book of Color. They have explained the genesis of the artist’s ideas (
Kapelush 1976;
Cahn 1995;
Zhadova 2007;
Wünsche 2015); documented these ideas’ connection to the theories of his predecessors and contemporaries (
Povelikhina 1975/76,
1999b;
Douglas 1986;
Galeyev 2005;
Wünsche 2012); explored Matyushin‘s “color vision” through his color charts in connection with his philosophy and worldview, as well as with the external circumstances under which it emerged in Stalin‘s Russia (
Tillberg 2002,
2003,
2011,
2013). To date, however, the color combinations presented in the
Reference Book have not yet received sufficient analysis from the point of view of the perceptual characteristics of colors (their hue, chroma, and lightness) and their combination criteria.
The purpose of this study is to fill this gap and to analyze Matyushin’s color combinations in the Reference Book of Color in CIELAB color space in order to obtain quantitative indicators of the variability of their chromatic characteristics and to visualize their correlations on the color circle.
2. Materials
In this study, we focus on the 34 color charts included in the first edition of the Reference Book of Color. The charts were intended to illustrate the laws governing the variability of color combinations described in the book. Like Matyushin’s color science in general, the charts were based on observations and experiments studying the psychophysiological factors of color perception and human color vision processes under different conditions.
In the original publication, the charts comprise four series (sections) of cardboard sheets (pages) sequentially glued together. Each of the first three sections contains eight color charts. The last, the fourth, includes ten more.
All the charts in the
Reference Book have the same structure. Each of them is a set of the following three colors (a “color triad” or “color chord”) (
Zhadova 2007, p. 10):
- (1)
The environmental background color;
- (2)
The “intermediary” linking color;
- (3)
These three groups of colors have different spatial functions.
The main active color is the color of the object. Under laboratory conditions this is the color of the body being observed, whose changes Matyushin and his disciples studied in their experiments (see, e.g.,
Nesmelov 2007, pp. 23–25). For example, a colored pendulum was swung from side to side to study color perception in motion. Or large colored cardboard circles were suspended at different distances from the observer in order to understand how color perception changes depending on the angle of view (see Introduction). However, in a broader sense, main colors might derive from any objects in a given environment—large details of interior and exterior architectural decorations, patterns on porcelain and wallpaper, or designs in textiles and print art.
The dependent environmental background color is the color that necessarily exists around the object’s color in a neutral environment, always accompanying it. This natural accompanying color supports the object’s color and significantly affects its expressiveness.
The “intermediary” color has a special role in the color chord. Its function is to link the object’s color with the environment, to create and maintain balance between them, without violating the spatial expressiveness of the main color as the leading one in a given composition.
The “quantity” of each color also plays an important role in the color charts’ structure. The charts’ bands of color samples have a height ratio of 3:1:6. That is, the background color occupies twice as much area as the main color and six times as much as the intermediary color of the middle stripe. The main color band is three times larger than that of the intermediary color. However, in his comments on the color charts, Matyushin explains that in real life and artistic practice it is not necessary to observe such a strict proportion in order to obtain a harmonious color combination. Most importantly, what is viewed as a background color should have the largest area, while the linking color should have the smallest one. Much more essential than quantitative ratios is the suggested sequence in space, i.e., the “intermediary” color should always be located between the main and the background colors (
Matyushin [1932] 2007, p. 33).
The charts were hand-painted with gouache by a group of young artists, Matyushin’s students, a year before the book’s publication. The team of artists included Irina Walter, Olga Vaulina, Sofia Vlasyuk, Valida Delacroix, Tatiana Sysoeva, and Elena Khmelevskaya (
Zhadova 2007, p. 7).
This manual manufacturing method of a significant part of the book explains the first edition’s limited circulation as follows: two years before Matyushin’s death, the State Publishing House of Fine Arts in Leningrad released only 425 copies of the
Reference Book (
Kapelush 1976, p. 11). Many of these books have survived in state collections in St. Petersburg and in private archives in St. Petersburg and Moscow and were available for our study.
3. Methods
For a quantitative analysis of chromatic characteristics, we measured all the colors of the Reference Book’s original hand-painted charts using a Konica Minolta CM 700d portable spectrophotometer (Konica Minolta Sensing Europe B.V., Nieuwegein, The Netherlands) with an 8 mm diameter aperture under D65 standard illuminant and 10° angle observer. The color coordinates were recorded in the 360–740 nm range with 10 nm spectral resolution and converted into CIELAB notation.
The CIELAB system is an internationally recognized color space that enables the description of any perceived color as three values (see e.g.,
Luo 2015b). Two of these values represent chromaticity. The a* axis correlates to the opponent red-green colors, and the b* axis to the opponent blue-to-yellow color scale. The chromaticity coordinates (a* and b*) can take positive and negative values. If a* is positive, the color has a “reddish” hue; if negative, it is “greenish”. With a positive value of b*, the color is located in the yellow area of the color space, and with a negative value, in the blue area. The third coordinate is lightness (L*), with values varying from 0 (black) to 100 (white).
To calculate the distance between two colors in three-dimensional color space, we used the following color difference metric:
(see e.g.,
Sharma et al. 2005;
Luo 2015a).
To facilitate visualization of each color within the CIELAB spherical color space, we transformed it into cylindrical coordinates to provide values for CIE hue (h*) and chroma (C*), or CIECh, as follows:
To quantify differences in perceived lightness (∆L*), chroma (∆C*), and hue (∆h*), we used the following Formulas (4)–(6):
For computing the triangles’ angles in CIELAB color space we used the following cosine Formulas (7)–(9):
where a, b, and c are color distances ∆E*00 between the main, intermediary, and background colors.
To assess the relationship between hue angles of the main, intermediary, and background colors we used the following circular correlation coefficient
pcc (
Jammalamadaka and SenGupta 2001, p. 176;
Berens 2009, p. 15) (10):
where
α and
β denote two samples of angular data and
the angular mean.
Since the authors of the
Reference Book of Color did not offer any color names for the selected colors (all of them were simply numbered in the tables), we “translated” them into a natural language in order to analyze their subjective perception. For this purpose, we correlated the color notations in the CIELAB color space with a database of color names from an open psycholinguistic experiment with native Russian speakers (for more details see:
Griber et al. 2018;
Paramei et al. 2018;
Griber et al. 2021).
6. Conclusions
Our CIELAB color space study of the color triads selected by Matyushin for the Reference Book of Color allows a number of important conclusions about the chromatic characteristics of colors (hue, chroma, and lightness) and their combination criteria.
Chromatic characteristics of colors. The Reference Book’s triads contain those colors that Matyushin and his disciples subjected to thorough experimental study in the GINKhUK laboratory.
For his main colors, Matyushin selects deep, high-chroma shades that are fairly evenly distributed in the quadrants of the color circle. These are as follows: red, orange, yellow, yellow-green, light blue, blue, and purple.
The charts’ environmental background colors, as a rule, are complementary to the main colors, and on the color circle are located opposite or almost opposite their corresponding main counterparts (cf.:
Figure 4 and
Figure 7). However, since his observations on color caused Matyushin to conclude that color combinations have maximum expressiveness under conditions of decreased chromaticity of the environmental background (
Matyushin [1932] 2007, p. 29), most of this group’s colors have low chroma (
Figure 7 and
Figure 8;
Table 2).
As for the preeminently important “intermediary” colors, their lightness noticeably correlates with the background colors, but in almost all charts they are significantly lighter than the latter (
Figure 14). Among the intermediary colors in the
Reference Book, fairly light blues and purples (
Table 3) with low to medium chroma predominate (
Figure 9). However, Matyushin aims to demonstrate that the same combination of main and environmental background colors can be harmonized by a linking color in several different ways, rather than one in particular. The choice depends on the practical task because, according to Matyushin’s deepest conviction, the intermediary color can diametrically change the overall impression produced by a color combination as follows: the intermediary color can enhance or reduce contrast, create depth, or add transparency, making the composition calm and comfortable or, conversely, active and stimulating (cf.
Figure 12 and
Figure 13).
The
Reference Book does not contain color combinations in which gray (achromatic) colors are considered the main colors. Matyushin intended to fill this gap in the book’s next editions (
Matyushin 1932, item 324). However, already in this work, he makes extensive use of grays as environmental and linking colors and, as such, demonstrates their properties in color combinations.
Art historians note that the charts’ color palette is consonant with Matyushin’s painting and “organically related” to it (
Zhadova 2007, p. 6). Essentially, the charts “translate” the artist’s painting into “another existence” (
Zhadova 2007, p. 8)—into architectural and spatial compositions. However, this observation, as well as Matyushin’s statement that a linking color can yield specific changes in the overall impression produced by a color combination, remains in need of detailed psychophysical investigation.
Color combination criteria. In his experimentation with color combinations, Matyushin relied on contemporary scientific ideas but used them in ways tempered by his judgment about “actual live color observation” (
Matyushin 2011, p. 286).
In particular, the phenomena of simultaneous and successive contrast play a special role in the color composition in the Reference Book charts. Experimental observations of these physiological effects inform the organizing principles for the color charts in the Reference Book.
Scholars of the artist’s creative biography and work (see, for example:
Zhadova 2007) note that Matyushin and his pupils showed great interest in the work of the French chemist Michel Eugène Chevreul, who in 1829 formulated the law of simultaneous contrast and ten years later published a book devoted to this phenomenon (
Chevreul 1839). Drawing on this work and their own experiments, the researchers built color chords based on the premise that, over time, any observed color begins to “generate” a complementary afterimage: red produces blue-green, orange—blue, and yellow—purple.
As a result, the triangles that triads always form in color space have a number of interestingly similar geometric properties. Plotted in CIELAB color space (
Tables S1 and S2,
Figure 17 and
Figure 18), they all have two long sides adjacent to the main color and one short side between the background and the intermediary colors. Most of the triangles are approximately isosceles. The longer triangles also tend to be wider. In all triangles, the angle adjacent to the main color is acute. In all charts, the area of the triangle depends on the lightness of the main, intermediary, and background colors as follows: the darker the colors, the smaller the area of the triangle.
All the triads also have a similar “geometry” on the CIELCh color circle. Here too, the intermediary color is much closer to the environmental background color than to the main color. In the different sections of the
Reference Book, the geometric pattern implied by these relationships does not change (cf.
Figure 15 and
Figure 16). Considering the same regularities of color combinations in various “lightness relations” (
Matyushin [1932] 2007, p. 31), the artist similarly demonstrates that decreasing the initial main color’s chroma makes the whole triad less chromatic (as in Section II) (
Figure S1). If, on the other hand, the main color has higher chroma (as in Sections I and III), noticeably darker background colors will support a harmonious color combination (cf.
Figure S1 and
Figure 14).
The application of color combinations. In general, laws derived from a basic level of observation, rather than rigorous scientific investigation, determine the variability of the Reference Book’s color combinations. Matyushin refrained from defining his color combinations by wavelength or pigments, as well as from any mathematical calculations.
As conceived by the Reference Book’s authors, their triads composed from 90 colors with different chromatic characteristics may serve as a convenient didactic tool to train the eye, intuition, and creative imagination.
The main idea of the
Reference Book is that color triads are not a “closed” but an “open” system. When working with them, one should not simply transfer the colors from the book to real environments but should play the role of co-author and engage in co-creation. The triads presented in the book need “adjustment” to the specific conditions of reality (
Matyushin [1932] 2007, p. 29). Thus, having understood the main principle of the variability of colors and their “geometry” in the color space, practitioners should independently compose the combinations they need and, considering the content and nature of practical tasks, may deviate more or less from the examples given in the
Reference Book.
We believe that the analysis presented in this paper will facilitate opportunities for artists, architects, designers, and other color professionals to use Matyushin’s original color charts and to incorporate Matyushin’s style in creating their own color triads.
