Silken Lighthouse
Five stops tuned to sit together without fighting — #006c77 ink anchors the set, #83e0ee opens it up, and #0099a9, #3ab5c6, #65c3d1 cross the middle in a analogous arrangement. Silken Lighthouse suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
