Acid palette
Kelp Foundry
Five stops tuned to sit together without fighting — #004b5f ink anchors the set, #71bbd6 opens it up, and #007593, #3190af, #549eb9 cross the middle in a analogous arrangement. Kelp Foundry suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
