Crimson Lagoon
Five jewel stops with room to breathe — #005668 grounds, #00819b and #349db7 do the talking, #5aaac1 softens, #77c7df lifts. The 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.
