This book - a series of lectures given in the early years of this century - is one of the pioneer works on colour and its effects on the human system. Steiner shows how colour has an objective effect on one's emotions, health and well-being, and on the basis of his spiritual-scientific research, he lays the foundation for a practical technique for working with colour that leads to new directions both in healing and in artistic creativity. This book is therefore an invaluable source not only for those wishing to know about colour therapy but also for artists and anyone interested in gaining an appreciation of art as a revelation of spiritual realities. 191pp, softback
