Claim Text:
1. A metal housing for an electronic device, the metal housing comprising: an edge defined by a first side and a second side that meet at a chamfer; a first anodization layer positioned on the first side and the second side, thereby defining a first interface surface between the first side and the first anodization layer, and a second interface surface between the second side and the first anodization layer; and a second anodization layer positioned on the chamfer, thereby defining a chamfer interface surface between the chamfer and the second anodization layer, wherein the chamfer interface surface has a more even topology than each of the first interface surface and the second interface surface such that the chamfer interface surface has a higher spectral reflectivity than each of the first interface surface and the second interface surface.
