Nautical palette
Steely Gazebo
Five nautical stops with room to breathe — #00464c grounds, #007179 and #308c94 do the talking, #5299a0 softens, #6eb5bc lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
