“The eye finds a physical satisfaction in green. When the mixture of the two colors which yield green is so evenly balanced that neither color predominates, the eye and the soul come to rest on the mixture as if it were something simple. We cannot and will not go beyond it. Thus green is often chosen for rooms where we spend all our time.”

—Johann Wolfgang von Goethe, from his Farbenlehre, or Theory of Color, 1808. Translated and edited Douglas Miller, 1988.
