Petrichor palette
Rustic Foundry
Dark anchor, working middle, light release: #00494e, #00747c, #318f97, #539ca3, #6fb9bf form a complementary petrichor set with somewhere to stand at every lightness. Made for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
