Blue Hour palette
Pale Canyon
Five blue hour stops with room to breathe — #004380 grounds, #296bb3 and #4586d1 do the talking, #6096d6 softens, #7bb3f4 lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
