Sorrel Harbor
Five blue hour stops with room to breathe — #005199 grounds, #397bc5 and #5597e3 do the talking, #6fa7e8 softens, #92c4ff 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 for large text.
