Polar Fen
Five stops tuned to sit together without fighting — #613c00 ink anchors the set, #d9a66a opens it up, and #955e00, #b2792c, #bb8a4f cross the middle in a triadic arrangement. Polar Fen suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
