The field of color imaging deals with the capture, processing, communication, and reproduction of color images. The origins of color imaging can be traced back to prehistoric times when cave dwellers created the first color drawings depicting events in their lives, using primitive materials and techniques available to them. Since then, color images have played an important role in history, and color imaging has advanced hand in hand with progress in science and technology. In the past 10 to 15 years, this field, like many others, has been significantly transformed by the digital revolution.
