Nautical palette
Velvet Clearing
Five nautical stops with room to breathe — #004a50 grounds, #00757e and #319099 do the talking, #549da5 softens, #70bac1 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
