Retro palette
Marigold Manor
Five retro stops with room to breathe — #0a358e grounds, #3460b8 and #4d7bd6 do the talking, #648cda softens, #7ea9f9 lifts. The tetradic 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.
