Prang's Standard Colors: For the Use of Teachers, Designers, Manufactures, Merchants, and Others who have Need of Standards of Colors
For the Use of Teachers, Designers, Manufacturers, Merchants, and 
Others who have Need of Standards of Color. 
These colors have been chosen and arranged in 
harmonious scales for the assistance of all who need 
definite and satisfactory standards of color for refer¬ 
ence, whether in Education, Art, Manufactures, or 
Trade. They have been fixed upon after repeated 
conferences with artists and color-experts. 
Mr. Prang’s 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 experi¬ 
ments 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. 
The definition of a scale of standard colors, cover¬ 
ing, to a practicable extent, the whole physical series 
of pure color, had Mr. Prang’s 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 varia¬ 
tions 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 con¬ 
struction of harmonious scales of standard normal 
tones. 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 inter¬ 
vals, 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 
The 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 pig¬ 
ments for coloring. 
The 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
