Fern Lighthouse
Five stops tuned to sit together without fighting — #007156 ink anchors the set, #84e7c4 opens it up, and #00a07b, #3bbd96, #66c9a8 cross the middle in a monochromatic arrangement. Fern Lighthouse suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
