Flannel Lighthouse
Five stops tuned to sit together without fighting — #005187 ink anchors the set, #7fc2ff opens it up, and #227abe, #4296dc, #62a5e1 cross the middle in a tetradic arrangement. Flannel Lighthouse suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
