Retro palette
Oyster Delta
Five stops tuned to sit together without fighting — #9f2c18 ink anchors the set, #ffb6a6 opens it up, and #cc5c47, #eb7862, #f28f7b cross the middle in a complementary arrangement. Oyster Delta suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
