About This Book

The manual explains color as an effect of light and presents yellow, red and blue as primary pigments from which secondary and tertiary hues are produced. It provides practical mixing rules and proportions for obtaining tints, shades, warm and cool variations, and advises how to lighten, deepen or neutralize colors using white, black and complementary tones. The text distinguishes organic and inorganic pigments, discusses sources and the role of mordants, and offers selection guidance for applied trades. It notes color-blindness as an occupational consideration and highlights color harmony, recommending nature as a model for balanced combinations.

PIGMENT

Pigment is any color preparation used by painters, printing pressmen, etc. Coloring matter is found in pigment cells of plants, tissues of animals and fish; in mineral form found in the earth, from coal, vegetables, etc.

Pigments may be divided into two classes, the organic and the inorganic. Organic pigments are compounds of carbon and the inorganic all other pigments.

Paints and printers’ inks are made from the same pigments; the difference is in the mordant. It all depends on the nature of the object to be colored. The mordant is the fixer which holds the pigment.

The selection of color material should be carefully made. Purchase from reliable dealers an assortment of reds, blues and yellows, some black and white.
