Blue Hour palette
Emerald Station
Five blue hour stops with room to breathe — #a14000 grounds, #e05d00 and #ff7b36 do the talking, #ff9867 softens, #ffc4aa lifts. The tetradic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
