The lectures summarized here are the result of forty years of Steiner's efforts to understand the essence of colors. A perspective on colors is developed that liberates the viewer from their subjectivity and leads them into the realm of objective laws. Such a consideration, which is not dependent on physical theories, allows one to grasp color in its fluctuations, in its life. Content (selection): Fundamentals of a spiritual scientific color theory for artistic creation, the color experience, the four primary colors, painting from color, light and darkness as two world entities, the two fundamental laws of color theory in dawn and dusk and in the blue of the sky, from spatial perspective to color perspective.
