Silken Brook
Five acid stops with room to breathe — #004949 grounds, #007475 and #318f90 do the talking, #539c9d softens, #6fb8b9 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.
