Seaside Fen
Five stops tuned to sit together without fighting — #005870 ink anchors the set, #78cae8 opens it up, and #0083a5, #359fc2, #5badcb cross the middle in a tetradic arrangement. Seaside Fen suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
