Halcyon Moor
Five stops tuned to sit together without fighting — #97341c ink anchors the set, #ffb4a0 opens it up, and #c36149, #e27d64, #ea927c cross the middle in a split-complementary arrangement. Halcyon Moor suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
