Ocean palette
Gleaming Granary
Five ocean stops with room to breathe — #004e63 grounds, #007898 and #3293b4 do the talking, #56a1be softens, #72bedb lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
