Blue Hour palette
Tawny Library
Five blue hour stops with room to breathe — #005f78 grounds, #008bae and #37a7cb do the talking, #5fb5d4 softens, #7cd2f2 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 for large text.
