When I encounter it, I immediately know. In “The Grandmaster” it is the use of black. It was very risky. We used hundreds of black fabrics. Different textures, glossy, less glossy, matte, very matte. Black with blue in it, black with brown, black with red. Velvet creates a very deep black. One day my assistant said: “Everyone is wearing black! Is it OK?” I said: “Don’t worry. I’m very sure.”
