Oaken Chapel
Five stops tuned to sit together without fighting — #9f2810 ink anchors the set, #ffb3a3 opens it up, and #cc5942, #eb755d, #f28c77 cross the middle in a split-complementary arrangement. Oaken Chapel suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
