Edit the metal bracket from the primary image: change its brown color to the dark graphite / anthracite charcoal gray color shown on the bracket in the reference image (RAL 7016 / 7024 shade). Keep the exact same shape, geometry, holes, indentations, material thickness, stamped rib contours, surface texture, glossy powder-coated finish with natural lighting reflections, and seamless clean pure white background intact. Only alter the color hue from brown to deep dark matte/semi-gloss charcoal gray.
