Calico Inn
Five stops tuned to sit together without fighting — #004c7b ink anchors the set, #85bce9 opens it up, and #3475a7, #5090c4, #6a9fcc cross the middle in a complementary arrangement. Calico Inn suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
