Color theory

“ We must expect, then, in painting, to find that neutral gray will be more altered by pale tints of red, orange, or yellow, which are slightly lighter than itself, and that the gray will be less altered by these colors when differing considerably from it in luminosity; analogous conclusions with regard to green, blue, violet, and purple, can also be drawn. Saturated or intense colors in a painting have less effect on white or gray than colors that are pale; this was shown in the preliminary experiment when gray was placed on a ground of strong color. ”

“ If it were not that colors can be compounded, we should be limited in hue and shade to the seven spectral colors; the wealth and beauty of color in nature, art, and commerce would be unknown; the flowers with their thousands of hues would have a poverty of color undreamed of; art would lose its magenta, its lilac, its olive, its lavender, and would have to work its wonders with the spectral colors alone. By compounding various colors in different proportions, new colors can be formed to give freshness and variety. ”

“ As an artist's color, it replaces almost all the other red pigments which we have inherited from the past. The same chemists have an equally powerful yellow and blue under careful observation, and it is highly probable that in another year or two these, also, will be given to the world. Now it is evident that if painters can secure these three primary colors in two values, a light and a dark shade, they will, with the addition of white and black, have a perfect palette ”

“ All the recent scientific writers on color treat this three-color scheme as already exploded, because the simplest as well as the most complex experiments with colored light prove its falsity. Nevertheless, the fact that yellow and blue, which with light make very nearly white, do in the mixture of pigments produce a green, has deceived many persons. ”

“ Contrast of color is perceptible in black when combined with color simply because the black is not perfectly black but a very dark gray, and hence there is the same complementary effect which shows in white and the lighter grays, but in a smaller degree. This effect is most clearly seen when the color used in combination is blue or blue-green, which induces in the black, yellow or red complementaries and gives the black a "rusty" appearance. ”

“ We are all born color-blind. The most perfect eyes in the world cannot see one-quarter of the colors which are known to exist in nature. Those of us who are fortunate, it is true, are able to differentiate with reasonable exactness the three primary colors which go to make up our limited human color-scale—but what about the tones which certainly exist above the ultra-violet band and below the infra-red? ”

“ Now, if blackness were the complete absence of light, the question as far as it is concerned would be much simplified; but I shall endeavor to show that black is not a negative impression. All black pigments and materials reflect light, and many of them to an extent which makes the fact readily demonstrable. Compare under a bright illumination half a dozen black things to be found in any home—cloths, book-covers, etc.—and it will be seen on a more or less close examination that they are not identical in appearance. Color-makers have their blacks of various intensities and shades. ”

“ Now we, as artists, could afford to ignore all this scientific side of the color question, were it not for the fact that it makes clear certain things which it is well for us to know. In the first place, it shows us the futility of any serious attempt to cultivate the sense of color. We are born with a certain given number of color-cones, and with just that allotment we must be content to go through life, for there is no known way of increasing their number, or of augmenting their efficiency. ”

“ Instead, therefore, of mixing upon his palette three primaries to produce the tertiary gray, he so places them on the canvas that at the proper distance (though this consideration is of small concern to him) the spectator will mix them—which he often does. The advantage of this method of color presentation lies in the degree of purity which the pigment retains. Its disadvantage appears in its frequent distortion of fact and aspect of nature, sacrificed to a scientific method of representation. ”

“ But we meet with slighter degrees of color-blindness, where the perception of red is not entirely wanting, but only considerably diminished; so that, for instance, an intense or strongly illuminated red can be perceived as such, while a less intense red appears green. This moderate degree of color-blindness does not always deter people from painting. A proof of this I saw at the last year's Exhibition, in a picture which represented a cattle-market. ”

“ All spectrum colors are pure, while no pigmentary color is absolutely pure, but the pigmentary color which approaches most nearly to the corresponding color in the spectrum must be selected as the pigmentary type of purity of that color. For example, the standard for green must be the best possible pigmentary imitation of the spot in the spectrum which by general consent is called green, and so not only for the six standards but for all their combinations which produce the other colors in nature. ”

“ In pigments these effects are imitated by the mixture of white with a color to produce tints, and black for shades, or more generally instead of black some dark natural pigment approaching the hue of the color, may be preferred because a black pigment will too often impart an unexpected and undesirable hue to the color. As for example, in making shades of red some natural brown pigment is better than black, and so various dark browns and grays are used for different colors. ”

“ When the eye has been fatigued by looking intently for a few seconds at a red spot on a white wall and is then slightly turned to the wall, a faint tint of a bluish green is seen, and this is called the accidental color of the red, and is supposed to be identical with its complementary color. If with the disks we determine a color which with a given color will produce by rotation a neutral gray, we have the complementary color more accurately than by any other means at present known in the use of pigmentary colors. ”

“ In consequence of this law of contrast of tone the contrast of black with active colors generally tends to intensify the black and lower the tone of the color, i.e., to weaken it as though white or light gray was mixed with it, but this effect is modified by contrast of color. ”

“ White and black represent extremes in color. Mixing of all the color rays of the solar spectrum produces white, and mixing of all the colors in the solid form of printing ink produces black. From this contrast of white and black maybe drawn a lesson in color. (Example 31.) Light represents warmth, darkness cold. As the colors are toward light they are warm; as they are toward darkness they are cold. Red becomes warmer as it takes on an orange hue, and colder as it takes on a purple hue. A warm color should be contrasted with a cold color—as orange with black. ”

“ Color preferences are often determined in this way; yet sometimes they spring from another and more radical source—an affinity between personal temperament and the feeling tone of the preferred color. A consistent choice of blues and grays indicates a specific kind of man or woman, very different from the chooser of yellows and reds.
Although single color tones are expressive, they seldom exist alone in works of art. Significant expression requires variety. The invention of original and expressive color combinations is a rare gift of genius. ”

“ One must remember always in studying color that we are treating with the material, not with the illusion. We are dealing with pigments, not with prismatic phenomena, and it must be obvious that the only three primary colors that can be used in a way to produce all other colors are red, yellow and blue. ”

“ Christian America created the color line; and all the great currents of critical opinion, from the eighteenth century to our time, have found the great barrier impassible and well-nigh impervious. Behind the color line one has to think perpetually of the color line, and most of those who grow up behind it can think of nothing else. Even when one essays to think of other things, that thinking is tinged with the shades of the surrounding atmosphere. ”

“ The vermilion shade of red is approximated by mixing white with orange-red.
The colored crayons with which the layout man should be supplied are exceedingly useful in determining color combinations. The eye is a reliable guide in this matter, if it is carefully trained to recognize color harmonies. It should be easy to distinguish the right from the wrong color treatment in Examples 5 and 6. The colder color should always predominate; backgrounds of bright red and bright yellow are difficult to harmonize with any color of ink excepting black. ”

“ When the pale or dark colors are not complementary to their more intense or brilliant rivals, they undergo the same changes indicated in the table on page 7, the changes in the case of the dull or pale colors being considerably greater. In proportion as the colors are distant from each other in the chromatic circle, do they gain in saturation and beauty; while, as they approach, their character is altered and they are apt to look very pale, or, in the case of the dark colors, blackish or dirty. This is particularly so when the brilliant color is large in surface and surrounds the darker one ”

“ Rough rules of color combination have been devised from the practice of artists and from experiment, the following of which will enable one to produce faultless patterns, but without genius will never enable one to create a new expression. Color combinations are either harmonious or balanced, the former produced by colors or tones of colors very close to one another, the latter by the contrasting or widely sundered. In the one case, we get the quiet commingling of feelings akin to each other; in the other, the lively tension of feelings opposed. ”

“ Pigments that are jet black and pure white either vegetable or mineral are unknown. It takes the addition of blue to alter the yellowish cast of white, and blue to deepen the brownish cast of any so called black pigment.
White being a neutral color, will harmonize with most any color combination.
NEUTRAL HUES AND TINTS Neutral hues are made by a 50–50 mixture of warm and cold colors. White added to neutral hues produce neutral tints. ”

“ A person totally color blind would see in the solar spectrum a band of gray in various tones, and hence if a red and a green should seem to be of the same tone of gray he would call both either red or green, and after much experience would come to give color names to various tones of gray. ”

“ As colour, according to the regular scale descending from white, ceases properly with the last of the tertiaries, olive, in theory the neutral black would here form a fitting conclusion. Practically, however, every coloured pigment, of every class or tribe, combines with black as it exists in pigments—not simply being deepened or lowered in tone thereby, but likewise defiled in colour, or changed in class. ”

“ We then shall have representations of all the spectrum colors, but there are still the colors between violet and red, known in nature and art as purples, which must be produced by uniting the red and violet disks, thus completing a circuit of colors containing all the pure colors in nature.
In nature all colors are modified by light and shade, strong light producing tints and shadows more or less deep forming shades. ”

“ Nature provides pigments of color to guard the skin against the inclemencies of sun and weather. Every modern man knows and 70has experienced the result of strong sun and wind in his own skin. “Tan” it is called, and sometimes, within a few weeks the color of a white man’s skin is transformed into a yellow or a dark brown. If the exposure continues, the color remains.
In the opinion of noted scientists, it is certain that the difference between the races as to color is merely skin deep. ”

“ Now when white is added to any hue or colour a tint of that colour is produced. If black is added a shade of that colour is produced. In the decoration of our rooms we shall see that as an actual fact we obtain shades of the colour by the omission of light, because the addition of black as a pigment to a colour acts in the same way as shutting off light. In mixing colours it is important to remember that black should not be used to lower the tone of a colour excepting in rare instances. It only has the effect of producing a muddy appearance. ”

“ Impure black is brown, but black in its purity is a cold colour, and communicates a coolness to all light colours; thus it blues white, greens yellow, [388] purples red, and cools blue. Hence the artist errs with ill effect who regards black as of nearest affinity to hot and brown colours, and will do well to keep in mind—"The glow of sunshine and the cool of shade."
It is a fault of even some of our best colourists, as evinced by their pictures, to be too fond of black upon their palettes, and thence to infuse it needlessly into their tints and colours. ”

“ Hence the judicious artist purveys for his palette at least two pigments of each colour, one eminent for delicate beauty, the other for richness and depth.
Truth of hue is a relative quality in all colours, except the extreme primaries, in the relations of which, blue, being of nearest affinity to black or shade, has properly but one other relation, in which it inclines to red and becomes purple-blue: it is, therefore, faulty or false, when, tending to yellow, it becomes of a green hue. ”
