Color is attractive and interesting to everyone. Consequently, control of color is important to all producers, buyers, sellers, and users of colored materials. In various ways, color is an indication of freshness, quality, or other desirable (or undesirable) characteristics of goods. To assure acceptability, saleability, and favorable price - especially in contracts and monitoring of conformance to specifications - numerical expression of color is greatly superior to verbal descriptions. Disagreements concerning words or visual comparisons with samples are all too likely and frequent. Such disagreements underlie much un pleasantness and loss in commerce in consumer goods. Such loss of money and good will must amount to billions of dollars per year, world wide. Persistent efforts to substitute measurements of color for visual judgment have marked the twentieth century. Because visual perception of small color differences is so acute, the requirements for accuracy and world-wide repro ducibility of color measurements have been severe. Only during the last half century have practical spectrophotometers with adequate accuracy been avail able.

Condizione: Fair. Aus Bibliothek aussortiert; Leichte Risse. Reviews and use of the first edition as the textbook for a senior-division uni versity course indicated the need for a number of corrections and clarifica tions. Although no new topics have been introduced, the new edition should be more clear and useful. A novelty in the Notes and Sources Appendix should facilitate reference from the notes back to the text. Far that purpose, the page number of the text to which each note refers is indicated in square brackets following the serial number of the note. The FMC1 color-difference formula has been substituted everywhere for the Friele-MacAdam formula, including the reference to the sources in Note 52. The FMC1 formula was actually used in the investigations reviewed in Sects. 8.3 and 8.4. The Friele-MacAdam formula given on page 151 of the first edition, which I thought was equivalent to the FMC1, was erroneous and should not be used. The formulas for the geodesic chromaticity diagram, on p. 153 of the first edition, were based on observations by 14 normal observers (last reference in Note 51). They have been replaced by the formulas based on the observations of PON, for consistency with all other formulas and discussions in the book. Figure 8.29 in the first edition was based on the PON data and on the formulas printed below it in the new edition. Therefore, Fig. 8.29 is un changed.
