Note: This part was colored by anodizing, which is a method of coloring metal. Color differences do occur among manufacturers and even among batches from the same manufacturer. This is not a flaw or imperfection, but it is inherent to the anodizing process. We make every effort to show accurate photos of products, but it is not possible to display every color variation. We are not responsible if a part doesn't match other items you own or is not the color you expected.
