Calico Lighthouse
Five stops tuned to sit together without fighting — #005275 ink anchors the set, #75c3f0 opens it up, and #007cae, #3398cb, #58a6d3 cross the middle in a complementary arrangement. Calico Lighthouse suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
