Blue Hour palette
Starlit Shrine
Five blue hour stops with room to breathe — #00536d grounds, #007ea3 and #349ac0 do the talking, #59a8c8 softens, #76c4e6 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.
