Autumn Gazebo
Five stops tuned to sit together without fighting — #005369 ink anchors the set, #78c4e0 opens it up, and #0c7e9d, #389ab9, #5ba8c3 cross the middle in a split-complementary arrangement. Autumn Gazebo suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
