Industrial palette
Midnight Bluff
Five industrial stops with room to breathe — #00515f grounds, #007c91 and #3397ad do the talking, #57a5b7 softens, #74c2d4 lifts. The complementary bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
