Five opera stops with room to breathe — #00487b grounds, #3571a6 and #508cc3 do the talking, #699bca softens, #84b8e8 lifts. The split-complementary bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
