The Revised Theory of Light The Principles of the Harmony of Color is a book written by William Cave Thomas and originally published in 1875. The book explores the principles of color harmony and the way in which light interacts with color. Thomas presents a revised theory of light, which he believes is more accurate than previous theories. He covers topics such as the properties of light, the nature of color, and the way in which colors combine to create harmony. The book is divided into several chapters, each of which focuses on a different aspect of the theory of light and color. Throughout the book, Thomas provides numerous examples and illustrations to help readers understand the concepts he presents. The Revised Theory of Light is a valuable resource for anyone interested in the science of light and color, and it remains an important work in the field of color theory to this day.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfect
