The invention relates to a light color coating for an electronic device. An electronic device may include a conductive structure having a reflective coating. The coating may have a double-layer film interference filter or a four-layer film interference filter. The double-layer optical filter can be provided with a CrN layer and a SiCrN layer. The four-layer optical filter can be provided with two CrN layers and two SiCrN layers. The double-layer optical filter can be used for coating relatively small conductive parts. The four-layer optical filter can be used for coating the side wall of a conductive shell. Both types of interference filters can produce a relatively uniform light blue color despite changes in coating thickness due to the geometry of the underlying conductive structure. 本公开涉及用于电子设备的浅色涂层。具体公开了一种电子设备，其可以包括具有反光涂层的导电结构。该涂层可以具有双层薄膜干涉滤光片或四层薄膜干涉滤光片。该双层滤光片可以具有CrN层和SiCrN层。该四层滤光片可以具有两个CrN层和两个SiCrN层。该双层滤光片可以用于涂覆相对较小的导电部件。该四层滤光片可以用于涂覆导电外壳侧壁。尽管由于底层导电结构的几何形状而产生涂层厚度的变化，但是两种类型的干涉滤光片都可以产生相对均匀的浅蓝色。
