(Robert) Experiments and Considerations Touching Colours (1664) Robert Shimmin, Keith Edkins, the PG Online Distributed Proofreading Team and David Widger "Experiments and Considerations Touching Colours" by Robert Boyle is a scientific publication written during the mid-17th century. The work aims to explore the nature, perception, and properties of colors, presenting a collection of observations and experiments primarily directed at a friend named Pyrophilus. Boyle seeks to provide a historical context to the concept of color, emphasizing the need for experimentation and inquiry rather than rigid speculation. The opening of the treatise introduces Boyle's intent to present a structured yet informal account of his various experiments and considerations regarding colors. He reflects on the challenges and complexities of understanding colors and hints at the importance of both empirical observation and theoretical frameworks in this pursuit. Boyle also discusses the significance of experimenting with colors, providing examples such as the tempering of steel and the psychological effects of colors on perception, while preparing readers for the detailed explorations that will follow in the ensuing chapters.
