Harbor Deck
Five stops tuned to sit together without fighting — #004467 ink anchors the set, #74b2de opens it up, and #1a6c9c, #3b87b9, #5896c0 cross the middle in a tetradic arrangement. Harbor Deck suits indie game interfaces with a strong day-night rhythm. The darkest and lightest stops clear AA as a text pair.
