Blue Hour palette
Drowsy Hollow
Five blue hour stops with room to breathe — #005cab grounds, #3086e1 and #50a3ff do the talking, #72b3ff softens, #a8d0ff 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.
