Original Abstract Submitted
an electronic device may be provided with conductive structures such as a titanium housing wall. a visible-light-reflecting coating may be formed on the titanium housing wall. the coating may have adhesion and transition layers and an uppermost opaque coloring layer. in a first example, the uppermost opaque coloring layer includes crc on a crsin transition layer. in a second example, the uppermost opaque coloring layer includes crn on a crn transition layer. the coating may exhibit a relatively uniform metallic silver or gray color that is smudge resistant even when the underlying titanium housing wall has a three-dimensional shape.
