Building on the achievements of Goethe in his Theory of Colour, Steiner shows how colour affects us in many areas of life, our health, our sense of well-being, our feelings. Distinguishing between 'image' and 'lustre' colours, he lays the foundation for a practical technique of working with colour that leads to a new direction in artistic creativity. It is an invaluable source of reference and study not only for artists and therapists but for anyone interested in gaining an appreciation of art as a revelation of spiritual realities.
