Sooty Gazebo
Five stops tuned to sit together without fighting — #364a8a ink anchors the set, #a5bbf7 opens it up, and #5d73b4, #778ed1, #8a9fd9 cross the middle in a monochromatic arrangement. Sooty Gazebo suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
