Industrial palette
Quiet Chapel
Five industrial stops with room to breathe — #00515b grounds, #007d8b and #3398a7 do the talking, #58a6b2 softens, #74c2cf lifts. The triadic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
