Halcyon Cellar
Five stops tuned to sit together without fighting — #534200 ink anchors the set, #c5af6a opens it up, and #816800, #9c832c, #a8934f cross the middle in a analogous arrangement. Halcyon Cellar suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
