Calico Lighthouse
Five opera stops with room to breathe — #004b69 grounds, #0075a0 and #3190bd do the talking, #559fc5 softens, #71bbe2 lifts. The complementary bones keep it coherent across packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
