Obsidian Heath
Five stops tuned to sit together without fighting — #004e53 ink anchors the set, #73bfc5 opens it up, and #007a81, #32959c, #56a3a8 cross the middle in a monochromatic arrangement. Obsidian Heath suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
