Sooty Lighthouse
Five stops tuned to sit together without fighting — #006e69 ink anchors the set, #83e3dc opens it up, and #009c95, #3bb8b1, #65c6bf cross the middle in a monochromatic arrangement. Sooty Lighthouse suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
