Golden Archive
Five stops tuned to sit together without fighting — #004458 ink anchors the set, #6db3ce opens it up, and #006e8c, #2f89a8, #5197b1 cross the middle in a monochromatic arrangement. Golden Archive suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
