Can we say when, where, and how the colours we see are formed? Are colours present like the flowers in a garden, or just an appearance? A simple, surprising fact, The Unified Principle of Colour, brings answers to age-old questions about colour and colour relationships. To the physics of light, and the biology of vision, a third discipline is added: the process of consciousness that enables perception. It shows that the observer, a living being, has an essential role in producing the colours we perceive.

About the Author

Peter Moddel was born in Ireland and currently lives in Gruyere, Switzerland. His studies in various disciplines (philosophy, literature, physics, pedagogy), the experience of living both in the West and the East, and periods of personal retreat fostered his reflections in philosophy, science and linguistics. Astronomy has been central in his activities and building telescopes expanded into an interest in vision and in colour theory. Understanding colour formation became a subject of personal research. Other passionate pursuits include hiking and music. He co-leads monthly caf�-philo encounters that aim to promote agility of thought and freedom from entrenched viewpoints.
