Birch Fen
Five stops tuned to sit together without fighting — #a93600 ink anchors the set, #ffc4b0 opens it up, and #e25a27, #ff7a4c, #ff9774 cross the middle in a split-complementary arrangement. Birch Fen suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
