    Abstract: An electronic device may be surrounded by an exterior region and may have an interior region. Electronic components may be mounted in the interior region. Housing walls such as housing walls formed from transparent layers of material may separate the interior region from the exterior region. A display may be visible through one of the transparent layers of material. A transparent layer of material may be coupled to housing structures in the device and may be formed of glass or glass-ceramic. The transparent layer may have two opposing chemically strengthened surface layers of different thicknesses. A coating may be formed on a thinner of the two opposing chemically strengthened surface layers. The coating may have an oleophobic outer coating layer, an antireflection layer, and an antiscratch layer. The antiscratch layer may have one or more compressively stressed dielectric layers and may have one or more corresponding graded composition layers.

    Abstract: An electronic device may include conductive structures having a visible-light-reflecting coating. The coating may include a seed layer, transition layers, a neutral-color base layer, and an uppermost layer that forms a single-layer interference film. The neutral-color base layer may be opaque to visible light. The interference film may include silicon and may have an absorption coefficient between 0 and 1. The interference film may include, for example, CrSiCN or CrSiC. The composition of the interference film, the thickness of the interference film, and/or the composition of the base layer may be selected to provide the coating with a desired color in the visible spectrum (e.g., at blue or purple wavelengths). The color may be relatively stable even if the thickness of the coating varies across its area.

The neutral-color base layer may be opaque to visible light. The interference film may include silicon and may have an absorption coefficient between 0 and 1. The interference film may include, for example, CrSiN or CrSiCN. The composition of the interference film, the thickness of the interference film, and/or the composition of the base layer may be selected to provide the coating with a desired color near the middle of the visible spectrum (e.g., at green wavelengths). The color may be relatively stable even if the thickness of the coating varies across its area.
