Synopses & Reviews
Numbering with colors is tutorial in nature, with many practical examples given throughout the presentation. It is heavily illustrated with gray-scale images, but also included is an 8-page signature of 4-color illustrations to support the presentation. While the organization is somewhat similar to that found in The Data Handbook, there is little overlap with the content material in that publication. The first section in the book discusses Color Physics, Physiology and Psychology, talking about the details of the eye, the visual pathway, and how the brain converts colors into perceptions of hues. This is followed by the second section, in which Color Technologies are explained, i.e. how we describe colors using the CIE diagram, and how colors can be reproduced using various technologies such as offset printing and video screens. The third section of the book, Using Colors, relates how scientists and engineers can use color to help gain insight into their data sets through true color, false color, and pseudocolor imaging.
