He both defends justice as lawyer Matt Murdock and confronts criminals at night in his costume. His color palette reflects this double life.
The intense red #c70132 symbolizes the fire of Daredevil's fight for justice, while the deep burgundy #680034 and #9c0135 hint at his dark past and the shadowy world he lives in.
