Retro palette
Steely Delta
Five retro stops with room to breathe — #7d0017 grounds, #b0333a and #cf5053 do the talking, #d66a69 softens, #f68684 lifts. The triadic 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.
