Russet Mesa
Five stops tuned to sit together without fighting — #6c2300 ink anchors the set, #ea8d6b opens it up, and #a54013, #c35c33, #cb7250 cross the middle in a tetradic arrangement. Russet Mesa suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
