Monochrome palette
Topaz Gazebo
Five monochrome stops with room to breathe — #1a679d grounds, #4e91c7 and #6aade5 do the talking, #84bcec softens, #acd9ff lifts. The analogous bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
