Acid palette
Flannel Crossing
Five acid stops with room to breathe — #004b58 grounds, #007689 and #3191a5 do the talking, #559faf softens, #71bbcc lifts. The split-complementary 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.
