r /Philosophy Of Color Published by Clifford & Lawton 19 UNION SQUARE, NEW YORK Copyright, 1904 By Clifford & Lawton The PHILOSOPHY ^?/COLOR 1. Color Nomenclatvire. HE harmony of color is a visible expression of one's mental joy. In music it is an estab- lished fact that certain notes used in combina- tion produce harmonious sounds. The moment that more than one note is struck, there is danger of discord, and when ten notes re- sound to the touch of the player, they must be the right notes, or the sounds jar upon the sensibilities. In the use of color the same law of exactness 6 Philosophy applies, and this treatise is an attempt to ana- lyze and understand the law. Color nomenclature includes three primary colors, three secondary colors, three tertiary colors, and innumerable shades and tints and modulations. All these colors bear relations to one another, either relations of analogy, like the relations of red to orange, or relations of contrast, like red to green. It is a knowl- edge of these relations of one color to another that must be grasped before one may success- fully produce results that are desirable. Let us first understand what constitutes pure color. When a ray of sunshine passes through a glass prism it is decomposed or separated, and if the prismatic colors are received upon a white screen, you will there find a pure blue^ a pure redy and a pure yellow. These are colors of the spectrum, and known as the primary colors ; and it is necessary, when speaking of any color, to bear these colors of the spectrum in mind as standards — a blue, for instance, that is the blue of the spectrum, of Color 7 and not a blue that is "prussian," "cobalt," or sky blue." In speaking of harmony, moreover, we must understand that there are two distinct kinds — the HARMONY of ANALOGY, which consists of the harmony of related colors or tones of one color, and the harmony of contrast, which is composed of colors in no way related. As an of example of 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 would mention red and green, because there is nothing in common between the two, red be- ing a primary color, and green a secondary, composed of the other two primaries, yellow and blue. Green is therefore called the complementary of red. Thus the complementary of . blue would be orange, because orange is formed by combin- ing the remaining primaries, red and yellow ; and the complementary of yellow would be violet, because violet is composed of blue and red, the other primaries. Definitions. Primary colors are blue, red and yellow. Secondary colors are orange, green and violet, each a combination of two primaries. Tertiary colors are colors made by combining two secondary colors ; tertiary colors are slate, rus- set and citrine. Quaternary colors are made by combining two ter- tiary colors. A COMPLEMENTARY color is that color of a set of three colors produced by combining two, which result is termed the " complementary " of the third color. Thus green is the complementary of red in the primary set, because composed of yellow and blue. Scale as in music relates to a sequence of notes of the same degree of tone. Luminous colors are warm colors — yellow, orange, red, hght tints of green, and some light tones of sombre colors. Sombre colors are blue, violet and the subdued tones of luminous colors. Cold colors are the same as sombre colors. Gray — A normal gray consists of pure black and white mixed. Where white predominates, it be- comes a light gray, and where black predominates, a dark gray. Philosophy of Color II Colored grays are normal grays to which a primary or a secondary color is added. Hue is the change produced in a color by the addi- tion of another color, although the original color must always be in the ascendency. Shade is the tone of color produced by the addition of black. Tint is the tone of color produced by the addition of white. Tones are the gradations of a color by adding either black or white. 12 Philosophy DIAGRAM I, 2. Composition of Color. HE above chart shows the manner in which the various colors are formed. Red, yellow and blue occupy the centre circle. The next circle is also divided into thirds, vio- let^ orange and green, and by examining same of Color 13 it will be seen that green contains one part each of blue and yellow ; violet contains one part each of red and blue ; orange, one part each of red and yellow. The third circle shows how slate, citrine and ^ . ^ j russet are made. For instance, slate is one Diagram part of violet and one part of green. Hence, a ScHemea RUSSET 3 RED 1 GREEN 2 SAGE A DIAGRAM II. 4 Philosophy o/Color tertiary color is made of equal parts of two secondaries. The three outer circles, olive, sage and plum, can be analyzed in the same way, sage, for in- stance, being composed of one part slate, with one-half part citrine. This diagram No. i is arranged to show not only component parts of a color, but the parts that properly harmonize. 3. TKe Contrast of Color. TN DIAGRAM 2 we have arranged at oppo- site points of the intersecting lines all of the primary, secondary and tertiary colors, marking the primaries i, the secondaries 2, and the tertiaries 3. It will be recalled that in re- ferring to harmonies of contrast we explained that a primary color contrasts with its com- plementary color, or the color made up by mixing the remaining two primaries. Thus red i6 Philosophy o/Color harmonizes with green, because green is made up by combining blue and yellow. This diagram shows the contrasting colors very clearly. Red, No. i, contrasts with the color immediately opposite, marked No. 2. Blue, No. I, contrasts with the color imme- diately opposite, orange. No. 2. Yellow, No. I, contrasts with the color on the end of the line, violet. No. 2. So on with the tertiary and quaternary colors. Russet, No. 3, contrasts with sage, No. 4. But the diagram. No. i, goes further into the subject. It is easy to understand that orange is a mix- ture of red and yellow, but it is not so easy to know what russet is, or what slate is, and it is still more difficult to analyze plum, sage and olive, without a chart. But once understand- ing that plum is a combination of one part rus- set and one-half part slate, and that russet is half violet and half orange, and so forth (see chart), it is easy to arrange any kind of har- monies — harmonies of related parts or harmo- nies of dissimilar or contrasting parts. 4'. TKe Decorative Application of Color. TT IS a safe rule in small apartments or apart- ments with low ceilings, or in cases where the decorator is not sure of his grasp of the sub- ject, to employ as the color scheme a three- color harmony of analogy. Or, we might take one of the three quater- nary colors, sagCy and combine with it the related tertiary and secondary colors : one part slate and one-half citrine, which compose sage; also, the constituent parts which make slate and citrine, or one-half violet, three- fourths green and one-quarter orange. These proportions are well worth a little study. Sage uses slate and citrine, but when we ana- lyze citrine we discover there is a little red in it, only to that degree wherein red enters into orange. Therefore, in using a pure red in a i8 Philosophy room with a background of sage, very little pure red is needed. Taking sage, then, as the tone of background, in order to determine a harmony of analogy we must combine with it all of its constituent parts in the proportions in which they occur. ^ Therefore, we draw an imaginary line between QxiicK A and B, which marks the composition of sage. Guide. We then discover the following analysis : Sage equals one part slate plus one-half part citrine. One part slate equals one-half part violet plus one- half part green. One-half part citrine equals one-quarter part green plus one-quarter part orange. One-half part violet equals one-quarter part blue plus one-quarter part red. One-half part green equals one-quarter part blue plus one quarter part yellow. One-quarter part green equals one-eighth part blue plus one-eighth part yellow. One-quarter part orange equals one-eighth part yellow plus one-eighth part red. Reducing the fractions we discover that, Sage equals the sum of one part slate and one-half citrine, or one and one-half parts or twelve-eighths. Slate, by the same reasoning, equals two halves or eight-eighths. Illustrating the composition and contrast of colors of the normal scale. Each of the three primaries in the centre harmonizes by contrast with the secondary color immediately opposite, and by analogy with all the colors back of it.

Green equals three-quarters or six-eighths. Orange equals one-quarter or two-eighths. Hence, the colors to be used in composition with sage as a background would be in pro- portions : Twelve parts sage, eight parts slate, four parts citrine, four parts violet, six parts green, two parts orange. In all, thirty-six parts, of which sage is one-third or twelve parts. If we take these proportions and apply them to a room or to a wall-paper or to any scheme of decoration, we can use them by applying sage as a background color of all, to be one- third in evidence when the work is completed ; or we can apply the colors to a white back- ground, using sage in the proportions herein- before described, so that twelve parts of that color shall be used in the decorations where only eight parts slate, four parts citrine, etc., are used. Let us take, for instance, a room that is in white woodwork, and apply the sage to the walls and the slate to the floor, and lighten the sage with citrine and lighten the slate 20 Philosophy (?/Color with violet, and intersperse orange and green in a way permitted by the proportions at our command. When the work is completed we find a harmony of analogy which can be then relieved by small touches of the primi- tive colors, blue, red and yellow, to sharpen and to emphasize. TKe /^RNAMENTS in color on a gold ground Flat J should be separated from the ground by an edging of darker color. Gold ornaments on a colored ground should be outlined with black. Ornaments of any color should be separated from the ground of any other color by an edging of lighter color, or white, black or gold, although ornaments in any color or in gold may be used on white or black grounds with- out outline or edging. 3. A. QviicK Way- of Determining Color HE letters RV mean reddish violet, being a violet having more red than blue in its composition. BV means bluish violet, being a violet having more blue than red in its com- position. BG means bluish green, being a green having more blue than yellow in its composition. YG means yellowish green, be- ing a green having more yellow than blue in its composition. YO means yellowish orange, being an orange having more yellow than red in its composition. RO means reddish orange, being an orange having more red than yellow in its composition. Thus a red may change to a yellow by gradations almost impercepti- ble, the change being the addition of yellow, little by httle, to a reddish orange, and so on, gradually, to an orange, continuing on to a yellowish orange, and, finally, to a yellow. The contrasting color at any stage may be deter- Contrasts. Philosophy - ( 1 4 1 ' 1 1 c 1 * 1 1 V ^\ 1 1 1 i - 1 .! t 1 1 I 1. TJ 1 ^ 1 1 \^ o \^ 1 1 I » { 1 1 1 I ^ ! ^ L r^^ ^ V- I J * !
