Midnight Lodge
Five stops tuned to sit together without fighting — #004375 ink anchors the set, #6cb2f6 opens it up, and #006ab5, #2e86d3, #5095d8 cross the middle in a tetradic arrangement. Midnight Lodge suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
