Industrial palette
Midnight Patio
Five stops tuned to sit together without fighting — #004b55 ink anchors the set, #71bbc7 opens it up, and #007684, #31919f, #549fab cross the middle in a tetradic arrangement. Midnight Patio suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
