Develop a logo for my law firm, Ricardo Câmara - Advocacy and Consulting, with an emphasis on professionalism, modernidade, autoridade e acessibilidade. Utilize cores associadas ao masculino e evite elementos tradicionais do direito. The name 'Ricardo Câmara' should be prominent in the logo. Busco um design limpo, elegante e original, possivelmente incorporando iniciais estilizadas 'RC'. A paleta de cores deve incluir tons de azul escuro, cinza e preto. Por favor, Provide the logo in a variety of formats and explain the copyright."
