One might reasonably expect that all would have been learned about color in the more than three hundred years since Newton established the fundamentals of color science. This is not true because:
• the measurement of color still has unresolved complexities (Chapter 2)
• many of the fine details of color vision remain unknown (Chapter 3)
• every few decades a new movement in art discovers original ways to use new pigments, and dyes continue to be discovered (Chapter 5)
• the philosophical approach to color has not yet crystallized (Chapter 7)
• new pigments and dyes continue to be discovered (Chapters 10 and 11)
• the study of the biological and therapeutic effects of color is still in its infancy (Chapter 2).
Color continues to develop towards maturity and the editor believes that there is much common ground between the sciences and the arts and that color is a major connecting bridge.
