Blue Hour palette
Atlas Dune
Five blue hour stops with room to breathe — #00556a grounds, #00809f and #349cbc do the talking, #5aaac5 softens, #76c6e2 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.
