Flickering Lighthouse
Five stops tuned to sit together without fighting — #0066a9 ink anchors the set, #b0d8ff opens it up, and #1c90e7, #4fadff, #75bdff cross the middle in a split-complementary arrangement. Flickering Lighthouse suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
