ABSTRACT
This chapter summarises the concept of chromaticity and its basic attributes for advancing its capabilities beyond those already established (Jones et al., 2008a). It indicates how chromaticity is related to pure measurement and the diagnosis of a condition. It explains how chromaticity quantifies information in terms of signal properties via an optimum of only three parameters. Approaches for extracting values of these three parameters via chromatic processors are described, and the manner in which these values may be displayed via chromatic maps and calibration graphs is indicated. The concepts of primary and secondary chromatic monitoring are explained, and the manner in which continuous and discrete signals can be addressed to check for emerging information about complex conditions is indicated. These aspects form the basis from which more recent advances have been made.
