Industrial palette
Walnut Delta
Five industrial stops with room to breathe — #00616b grounds, #008e9c and #38aab8 do the talking, #60b8c3 softens, #7dd5e1 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.
