Snowy Cellar
Five stops tuned to sit together without fighting — #004b55 ink anchors the set, #71bbc7 opens it up, and #007684, #31919f, #549fab cross the middle in a split-complementary arrangement. Snowy Cellar suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
