Copper Library
Five stops tuned to sit together without fighting — #045692 ink anchors the set, #90c8ff opens it up, and #3f80bc, #5b9cda, #75abe0 cross the middle in a monochromatic arrangement. Copper Library suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
