Crimson Station
Five stops tuned to sit together without fighting — #83001a ink anchors the set, #fa8a89 opens it up, and #b4383f, #d35558, #da6e6e cross the middle in a tetradic arrangement. Crimson Station suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
