They have been fixed upon after repeated conferences with artists and color-experts.\nMr. Prang\u2019s work for over fifty years has included large enterprises in the line of color printing, and the reproduction of paintings in oil and water color. Many years ago he began his experiments for definite standards of color, the great need of which has always been felt by those who use color materials in the arts and industries. In the course of his work he came to feel strongly the value of color study as a part of general education, and he continued his experiments with the definite purpose of producing, in a practical, material form, a series of colors as a basis for color instruction in the schools, and as a standard of reference in the arts and industries.\nThe definition of a scale of standard colors, covering, to a practicable extent, the whole physical series of pure color, had Mr. Prang\u2019s first consideration. The only flowing band of color in nature is to be found in the solar spectrum ; but this is incomplete as a physical series of color, and it has not the stability necessary for a proper guide. The variations of the colors composing it, in hue, in intensity, in absolute and relative luminosity, influenced by the time of day and by atmospheric conditions, are such that no reliance is to be placed on it for the construction of harmonious scales of standard normal\nfi)\ntones. Nature here, as in all its phenomena, can serve man only as a study for the recognition of the underlying laws : it is his mission to evolve ideals based on these laws. It was recognized by Mr. Prang that the complete physical series of color contained in the wave of white sunlight presents the unit of pure color, and as nature nowhere gives all these colors in combination, the true unit of color has to be imagined. Accordingly, he took for his color-unit an ideal of the colors potentially existing in a wave of white light. A harmonious scale of colors, covering this unit in twenty-four equal intervals, was then made, not as a mere copy of certain colors of the solar spectrum arbitrarily chosen, but as the result of careful weighing and judging, under the guidance of educated color perception and feeling.\nThe determination of tones for the standard scale of a normal unit color has been derived largely from j artistic and educational considerations, influenced at the same time by the practical requirements and limitations found necessary in the choice of pigments for coloring.\nThe first stage of work in this color scheme was the painting of models, not only for a series of twenty-four standard normal tones to cover the unit in equal intervals, but also models for all tones in the whole scheme, in order to admit of the judging of the scheme as a whole, and at the same time in all its parts, so as to secure harmonious relations at once between the parts themselves and between the","page":1},{"file":"p0002.txt","language":"en","ocr_en":"THE TWENTY-FOUR COLORS OF THE COLOR UNIT,\tTHE SEVEN GRAYS\nt> P\t' ;>w\tg\t\to > P\n& i-3 \u00ab p\t\u00ab ^\t' a5 cq\tl^n\tQ pa n\n^ J a, P\teS' j o J\ts5> a\t^ C o M\t& P ss P\n<\u00a3> J \u00a3 J\t\u00ea*j\t\u00a3\t^ es S* R\t& R P R\nP O i-3\to ^\t& O\to^0 o M\tcS' g O P\nc\u00a3* J K t-3\tprj\tPS\tJ \u00ab\t& P P P\n\t& j\tc\"\ta\" p\t>* Q \u00ab p\nRRV LL\t\u00e8 p P\tw~ os\tRRV D\tRRV DD\nRV LL\t\u00e8 J\t5s\ta AU\tP p w P\nr g j c -j\tL IJ\tVRV\t> g p\t>, P \u00a3 \u00ab\nV LL\t> p\t>\tV D\tV DD\nVBV LL\tVBV L\tVBV\t> S o\tg: P g P\nBV LL\tBV L\tBV\tBV D\t> P os p\nBBV LL\tBBV L\tBBV\tBBV D\tBBV DD\n\u00ab J\tSS s\t03\tes p\tp g\nBBC LL\tBBG L\tBBG\tBBG D\tS g pq Ph\np J P j\tB G L\tB G\tBC D\to p p p\n!

These models, executed in the most permanent pigments now existing, were to serve as guides for the manufacture of Prang\u2019s standard colored papers, and thus insure a continuity of the once-adopted hues as nearly perfect in every edition as experienced workmen can produce.\nThe diagram on page 2 shows the plan and scope of the scheme of scales based on the twenty-four normal standard hues, covering the unit of pure colors.\nTo these scales of pure colors a scale of neutral gray and six scales of \u201cbroken\u201d colors were added. These latter are based on the six leading colors of the color unit, \u2014 red, orange, yellow, green, blue, and violet, \u2014 broken by gray. They give us examples of the colors known by artists as tertiaries \u2014 russet, citrine, and olive \u2014 as well as \u2022 brown, slate, and heliotrope.\nMANUFACTURE OF THE PAPER.\nWhen Mr. Prang had completed his models, he took up the next stage of the work, the reproduction of the colors on paper, so as to get a series of colored papers. In the coating of these papers he met with considerations which restricted the choice among available pigments in producing the colors, as they had to meet certain conditions connected with their use.\nThese conditions were : \u2014\nI.\tFreedom from arsenic, which enters into the manufacture of some otherwise very desirable pigments.\nII.\tPermanency, as far as the choice between available pigments permitted.\nIII.\tAdaptability for coloring of paper.\nThe first condition has been met absolutely. The second condition has been met as far as possible by a choice among pigments restricted by the other paramount conditions. For this reason the paper manufactured falls, in some respects, short of\nMr. Prang\u2019s models, but will be found sufficiently perfect to be of great service for educational and artistic purposes, if not so immediately helpful to the scientist.\nIn the simple and clear nomenclature which Mr. Prang has adopted for his standard colors, he followed other authors on the subject. The color names of the unit scale will be easily understood if the reader recalls the familiar names of the points of the compass, only assuming six instead of four cardinal points ; viz. red, orange, yellow, green, blue, and violet.
