Tidal Crossing
Five stops tuned to sit together without fighting — #990040 ink anchors the set, #ffa1b2 opens it up, and #ca3f66, #ea5d80, #f07892 cross the middle in a tetradic arrangement. Tidal Crossing suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
