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.

TO MATCH SPECIAL COLORS

In mixing special colors or shades for large jobs, first mix a small quantity, write down exact proportions either by weight or volume, keep a record for future reference.

If you have failed to keep a record and have a small quantity on hand and wish to duplicate it exactly, put a small amount on a piece of white paper and after mixing a little dribble or let it string across the original sample you can get a perfect match. Still another way; brush a small quantity on a piece of transparent glass, add a like amount of the paint you mix beside it and hold to the light.

To match a specimen in printing ink; mix the color (small quantity), ink up press, pull an impression then with your make ready knife cut a small hole (any shape) in the most solid part of print, lay this over a solid part of sample.
