Comparing Colour Theories: Newton, Goethe and Contemporary Scientists

Introduction

Colour theories have taken various approaches throughout the centuries, ranging from the physical principles established by Isaac Newton to the psychological insights of Johann Wolfgang von Goethe and the more complex models developed by modern scientists. Each of these theories has, in its own way, contributed to our understanding of colour and its application in art, science and technology. This comparison examines the core ideas of Newton, Goethe and contemporary scientists, and how they relate to one another.

Isaac Newton: The Scientific Foundation

Isaac Newton's work in the 17th century laid the foundation for modern colour theory. Newton demonstrated that white light, when passed through a prism, splits into a spectrum of colours. In doing so, he proved that colour is a property of light itself, determined by the wavelength of the light. Newton developed the concept of the colour spectrum and showed that different colours can be combined to form white light. His approach was strongly rooted in physics and based on experimental evidence.

• Core ideas: Colour as a property of light, the colour spectrum, wavelengths.
• Contributions: Laid the scientific foundation for modern optics and colour theory, and influenced the development of colour models such as RGB.

Johann Wolfgang von Goethe: The Phenomenological Approach

Johann Wolfgang von Goethe, an influential German thinker, responded in the 18th and 19th centuries to Newton's approach by focusing on the subjective experience of colour. Goethe believed that colour could not be explained solely by the physical properties of light, but also by the psychological and emotional effects that colours evoke in people. In his work “Zur Farbenlehre”, Goethe introduced a colour circle that focused on the relationships between complementary colours and the emotional impact of colour combinations.
