Blue Hour palette
Frosty Estuary
Five blue hour stops with room to breathe — #003f73 grounds, #1e67aa and #3c82c7 do the talking, #5892cd softens, #74aeeb lifts. The analogous bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
