“History provides many examples of how rulers have coveted purple. Surroundings in this color are always serious and magnificent.

Purple glass shows a well-lit landscape in an awe-inspiring and terrible light. This must be the color cast over heaven and earth on the day of judgement.”

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