Butter Cottage
Five stops tuned to sit together without fighting — #005241 ink anchors the set, #74c4ac opens it up, and #007f66, #339a80, #57a790 cross the middle in a tetradic arrangement. Butter Cottage suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
