Stormy Canyon
Five stops tuned to sit together without fighting — #9a4327 ink anchors the set, #ffc2ae opens it up, and #c66f53, #e48b6e, #ed9f86 cross the middle in a analogous arrangement. Stormy Canyon suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
