Abstract
An electronic device may be provided with conductive structures such as conductive housing structures. A visible-light-reflecting coating may be formed on the conductive structures. The coating may have adhesion and transition layers and a multi-layer thin-film interference filter on the adhesion and transition layers. The multi-layer thin-film interference filter may have an uppermost SiCrN layer, a lowermost TiN layer, and a set of SiN layers interleaved with a set of SiH layers. The coating may exhibit an orange, yellow, or red color that has a relatively uniform visual response at different viewing angles even when the underlying conductive structures have a three-dimensional shape.
