Sunset Pier
Five stops tuned to sit together without fighting — #7d0026 ink anchors the set, #f68691 opens it up, and #b03349, #cf5062, #d66a76 cross the middle in a tetradic arrangement. Sunset Pier suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
