Satin Reef
Five frost stops with room to breathe — #00494c grounds, #007479 and #318f94 do the talking, #539ca0 softens, #6fb9bc lifts. The analogous bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
