Perennial Deck
Five stops tuned to sit together without fighting — #00616b ink anchors the set, #7dd5e1 opens it up, and #008e9c, #38aab8, #60b8c3 cross the middle in a split-complementary arrangement. Perennial Deck suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
