“ Crimson, red, scarlet, orange, yellow, greenish yellow, green, bluish green, blue, violet, and with added red get back to crimson.A room or a series of rooms may run to all colors and be still a harmony of analogy if the sequence or succession is gradual.35. No more delightful harmonies can be imagined than those provided by nature. One may start with the brown of the earth and run into several shades of green, and from that touch upon yellow, and from yellow to orange, and from orange to red, and red to violet, and violet to the blue of the sky. ”

Biographical details
C. R. Clifford, best known for his seminal work Color Value, examines the complex interplay between color, light, and spatial design. His writings highlight balanced color schemes, the influence of illumination on color perception, and practical uses in interior decoration.
By conducting a methodical study of primary colors and their interactions, Clifford connects abstract principles with real-world design challenges. His work continues to serve as a fundamental resource for understanding color dynamics in architectural and decorative settings.
Quotes by C. R. Clifford
“ The pale tints of electric lights, which make every face in a room look ghastly, will affect quite as disastrously every soft color in the furnishings. In ordinary gaslight a pair of white gloves looks yellow, and we have seen Welsbach lamps which threw out a violet-blue illumination, depressing in the extreme. Under a yellow glow, blues, greens, violets and purples are greatly changed. Under a violet glow, yellows and greens are ruined. To see all colors in about the same value that they possess by daylight one must have a light in which no color tone is apparent. ”
“ If our furniture is white and gold, it is clearly evident that the colorings of a room should be soft and harmonious. If we adopt the dark teakwood of India or the deep brown of Flanders, our color scheme again changes. ”
“ 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. ”
“ The harmony of contrast consists of colors in no way related. As an example of the harmony of analogy, we would mention red and orange, because both of these colors have ingredients in common, red being one of the two component parts of orange. As an example of the harmony of contrast, we suggest red and green, because there is nothing in common between the two, red being a primary color, and green a secondary, composed of the other two primaries, yellow and blue. ”
“ The most effective room is the one lighted in various degrees of strength, and while the decorator unconsciously follows this idea and avoids superabundance of pattern by using panels, friezes and wainscotings, we believe that each and every section or part of a room should be treated separately, observing, of course, a consistent spirit of design, preserving the period style and the general color effect ”
“ Many houses are left in the white plaster for a year or more until the plaster settles. In this condition a small unit of light is sufficient, but when the decorator completes his work, adding fabrics and wall-papers which absorb and diminish the light, the householder, unaware of the cause, notices a material increase in his bills for illumination. These facts must be understood to be remedied, and it remains for the illuminating engineer to determine by direct experiment the value of any light as it affects and influences color, as well as the value of color as it affects light. ”
“ The family relations of red are the things which go with red. We may have a harmony of analogy in violet which includes the relations of red and blue. We must not attempt to carry the family relationship too far. There is a wide range of variety in these combinations of analogy because they may include not only all scales of each color from the darkest tones to the lightest tints but they include tertiaries and quaternaries. [Pg 70] Each man must establish his own standard, and by establishing it he forms unconsciously a very comprehensive understanding of color. ”
“ Luminous or advancing colors make a small room look all the smaller; therefore in small rooms we suggest the use of white woodwork, and in the color treatment we would avoid contrasts, but would suggest harmonies of analogy in receding colors, soft grays, greens and blues. These are not luminous colors and will make a small room look the larger, while the white will give light effects, and if the room appears a trifle somber it can be easily relieved by [Pg 44] the bright colors of the bric-à-brac and by a touch of gold here and there on the wall. ”
“ In music, a tone which is formed by a certain number of vibrations per second is the same the world over, and each and every tone has a name; but in color no such standards exist. People have attempted to formulate a system by denominating the primary colors, red, yellow and blue, respectively as R, Y and B, and the combinations of these colors as combinations of letters. For example, red, with varying degrees of yellow added, is denominated by the letters R R O, or R O R, or O O R. This system tends to confusion, and is inadequate to express tints and shades. ”
“ Good decorative illumination does not mean illumination that reveals every hidden corner of a room. We need shadows to betray form, relieve monotony and give depth to the ensemble. If in an illuminated area light is of a uniform intensity, we have a bad effect. ”
“ If we have clearly in our minds the appearance of the normal red and yellow, and clearly in our minds the orange that is made up by combining the two, we ought to be able to fix in our imagination the colors that come midway between the red and the orange, or the colors that come nearer the red or nearer the orange. ”
“ As one’s appetite for the thing that is sweet becomes exhausted by a superabundance of sweets, so the eye resting upon a mass of red in the dress of a woman fails to appreciate the red tint in the face, and the face thus juxtaposed becomes pallid. A red-faced woman often wears brighter red in dress, so that her face may appear less red. The blue dress gives yellow to the face; the yellow dress gives blue; these results are altered materially by the intervention of white between the face and the dress. White intensifies color. ”
“ In small rooms harmonies of contrast are unsafe, because contrasts must involve advancing colors, which make a room look smaller. (See ¶ 86 and ¶ 90.) Harmonies of analogy are far better; and as frieze, wainscoting and dado are not recommended in the small room, we suggest that the furniture woodwork and the wood trims should be of one color note, unless it is desired that the wood trims should be white; and that the side-walls, curtains and chair upholsterings should be of a note in some degree related and of receding color, picked out with just a touch of contrasting color. ”
“ The sense of color is a nerve sense, and this sense varies in the individual. We know that colors which are strongest in direct sun rays, like red and orange, arouse the normal senses, while the blues and violets quiet.Nature provides vast fields of green because favorable in its effects upon humanity. Experiments prove that men of extreme sensibility exposed to the influences of red light finally show excitement which gives muscular development fifty per cent. ”
“ Royal purple and Venetian blue are mere trade terms. Practical men in the purchase of things decorative soon discover that color terms convey only individual impressions and no distinctive qualities that may be relied upon; so that any effort to fix the color value by periods would be futile. We may assume that in the age of oak, mahogany, white and gold or walnut furniture, the fabric and wall colors harmonized with the wood colors, and to that degree we may fix the period character of color. The moment that the tone of the woodwork or the light conditions varied, color character varied also. ”
“ But the effect of color is exciting or disturbing, tranquilizing or pleasing, inexplicable and inexpressible, affecting the senses like an appeal to the passions or the appetite. One might as well explain the love of sport, literature, art or vice. ”
“ In every room there must be a prevailing or dominant color, and the use of a contrasting color must be limited to proportions which give simply a pleasing emphasis. Let us assume that a room has a deep frieze pronouncedly green. ”
“ Color, like music, while subjected to positive rules of harmony, appeals to natures according to the responsiveness of their nerve sense, and the practical decorator in dealing with a customer should discover at the outstart the character of that nerve sense. Some natures respond to the normal colors, barbaric colors. Some respond to the softer tints and are disturbed by the sharper tones. A dulled sense requires sharp contrasts; a quickened sense is satisfied with the soft gray tones. ”
“ In the color treatment of a room one has either to adopt a harmony of analogy or a harmony of contrast, and this is a matter which depends upon so many conditions that it should be carefully considered. ”
“ But while the technical man or engineer may have a knowledge of power and energy, he has not studied the decorative value of lighting. His problem has been economic rather than psychologic. The illuminating engineer cannot be expected to appreciate fully the harmonies of color in decoration.137. It is the decorator’s province to consider not only the power of light in the furnishing of a house, but the character of the light—not only its color influence, but the structural character of its introduction, as affecting these furnishings. ”
“ LIGHT, COLOR, FORM, PROPORTION AND DIMENSIONSWhatever is good in interior decoration is the result of consistent relationship between Light, Color, Form, Proportion and Dimensions. The choice of Color should be guided by the conditions of Light. The beauty of Form and the symmetry of Proportion can exist only by a balance with Dimensions.Therefore, apart from any knowledge of historic or period decoration, effective or successful work must observe the technical laws governing conditions.LIGHT1. ”
“ Very often the specifications are finished before the color scheme has been decided upon, and as a result the degree of [Pg 79] illumination either falls short of what is needed in case of dark-colored interiors, or proves excessive with light-tinted rooms. The architect works from one point, economy, the decorator from another, æsthetic; while the householder, the consumer who pays the illuminating bills, cannot comprehend why his lighting bills increase as his taste for luminous or dark-colored furnishings is gratified. ”
“ In the use of one color with another of contrasting character the question frequently arises, what proportion of each should be used to obtain the best effect? Illustrative color books show usually samples of color of the same size, leading one unconsciously to the error that contrasting colors should occupy the same surface dimensions. ”
“ Citrine is an advancing color, because while it contains some blue in the green of its composition, it contains a preponderance of yellow and orange; slate is a receding color, because while it contains some yellow in the green of its composition, it contains a preponderance of blue; in the same way plum may be regarded as an advancing color, because of its preponderance of red; buff is an advancing color, because of its preponderance of yellow; sage is a receding color, because of its preponderance of blue. ”
“ We very often notice a room which has been carefully carried out but is utterly lacking in charm. The color seems right, and, considered in detail, the furniture and the furnishings are appropriate, but the room lacks effectiveness. ”
“ Bear in mind that natural light as it appears out of doors is materially altered when indoors by the presence of different planes and angles, which cast and receive various depths of shadow; the quality required is that which will provide illumination without glare. The sun’s rays are softened and mellowed by the depth of air through which they pass, and it is this mellowness that is the chief requisite in illumination. ”
“ The lighting of a house is a matter so dependent upon æsthetic conditions that it is never within the scope of the electrician. It is a problem for a decorator alone to solve. Intense and glaring lights of unusual power must be avoided. Luminants of low intrinsic brilliancy are preferable.155. The floor is the least important surface for illumination, and has no reflecting power of value. The walls vary in value according to their color and surface. With lights radiating upward, however, the ceiling possesses definite power, and should be considered. ”
“ For the drawing-room and reception-room it is desirable that all parts of the room be evenly lighted, without a pronounced glare in any particular part of the room. One of the most effective ways of accomplishing this is by distributing the lights around the room, either on the ceiling, in the cove or above a wide molding, so that the ceiling acts as a reflecting agent, and distributes an even tone of light to all parts. ”
“ In considering artificial light, we will avoid all efforts to analyze the different forms of energy, magnetic energy, electric energy, heat energy, mechanical momentum, radiating energy, and deal with result rather than with cause and effect. It will be sufficient to state as the deduction of the scientist that certain waves or vibrations which affect the fibers of the optic nerve are transmitted by the brain into color. (¶ 3.) Self-luminous bodies are bodies which produce light. ”
“ We do not wish to be understood as stating that the work of the colorist is solely mechanical; but we would emphasize that the influences of color are very largely the result of studied proportions. The basis upon which one operates must be soundly constructed upon the theory of scale, and scale is mechanically determined. ”
“ We all know that a northern exposure gives a room a deficiency of sunlight, and the wall treatment should supply this. A southern room, on the other hand, gives so much sunlight that counteracting wall treatments in cold color are permissible. ”
“ In a room 20 x 20 feet, with furnishings of mahogany and green, broken up by bookcases and other furniture producing heavy shadows, it is estimated that twelve eight-candlepower lights are sufficient if worked into the frieze, and that a reading lamp of not less than thirty-two-candlepower be used as a drop light.Assuming a room is 15 x 15 feet, and furnished in light tones, four eight-candlepower lamps are ample.A living-room 20 x 25 feet, in light tones of color, requires two thirty-two-candlepower lights, centrally located, and about twelve eight-candlepower lights. ”
“ The introduction of light by the medium of a wire, which may be carried to any point in a room, encourages so many possibilities for comfort and effect that it behooves us to forget traditional customs which were established during the gaslight period. ”
“ In practical demonstrations the study of color will be confusing unless it is understood at the outstart that pure prismatic colors can seldom be found in manufactured pigments, hence any demonstration of the theory of color composition is usually unsatisfactory. ”
“ A space that is arched looks wider than it actually is, for the eye unconsciously follows the lines of the arch, and a distance or width effect is the result. The same space treated with a straight line is quickly bridged. The same space treated with lines that come to an angle looks narrower, for the reason that the eye becomes focused by the apex of the angle, and a height effect, not a breadth effect, is the result. ”
“ White is worn universally by men and women next to the face, in collars or in neckwear, and the reason for it is that the contiguous white intensifies whatever color they may possess. Black, on the other hand, lessens the color or lowers its tone.32. Gray is a medium between the two. While it renders an adjacent color less brilliant, it takes to itself at the same time a tint that is a complement of that adjacent color. ”
“ Where the artist has but one room to consider there is little scope for his application of color knowledge. He must frequently compromise to meet the conditions. But presuming that he must treat a floor through, he should adopt a Unity which will apply harmoniously to all the rooms and hallways. ”
“ The hallway is rather dark. The living-room has only one window, and requires more warmth of color than the billiard-room and dining-room, which being sunshiny can be treated in more sombre tones. Therefore we select combination 6 for the hallway. The one room on the right we treat in No. 1. The rooms on the left we treat in Nos. 5, 4 and 3. We have, therefore, as we stand in room No. 6, treated in green, citrine and orange, a view to the right of yellow, orange and red, which is in harmonious juxtaposition. ”
“ A dense cloud which appears nearly black when between the observer’s eye and the sun, owing to the degree of density with which it intercepts the light, may become brilliantly white when the sun’s rays fall upon its constituent particles, for the light which cannot penetrate the cloud is continually reflected to and from the surface of its minute parts. ”
“ The rugs, frieze, wainscoting or dado, furniture upholsterings and the curtain borders should be related. (See ¶ 49.) 55. If the curtains have no borders, then the curtains contrast with the wood trims.56. Remember always cove and ceiling should be the palest tint of the side-wall color, and the rug should be of the deepest contrast to the side-wall, in harmony with the wainscoting, if there is a wainscoting. Remember, also, that the colors here prescribed are never to be of the same scale. The rug or carpet is of the deepest, and the ceiling of the palest. ”
“ Diagram III is of the utmost value to the colorist, illustrating not only the composition of color, but showing the origin of each secondary from the two primaries, the origin of each tertiary from two secondaries, and of each quaternary from two tertiaries. ”
