Monochrome palette
Frosted Delta
Five stops tuned to sit together without fighting — #006c76 ink anchors the set, #83e0ec opens it up, and #0699a7, #3cb5c4, #66c3cf cross the middle in a split-complementary arrangement. Frosted Delta suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
