Petrichor palette
Calico Brook
Five petrichor stops with room to breathe — #007280 grounds, #00a0b3 and #3cbdd0 do the talking, #68cadb softens, #86e8f8 lifts. The complementary bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
