Gleaming Harbor
Five stops tuned to sit together without fighting — #7c3325 ink anchors the set, #eca798 opens it up, and #a75d4e, #c57868, #ce8b7d cross the middle in a triadic arrangement. Gleaming Harbor suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
