Abstract: A reflective member having transflective and substantially opaque regions is disclosed. The transflective region may serve as a sensor opening region. When viewing the member from a first direction, the difference between a total light reflectance of the member at the substantially opaque region and at the sensor opening region is less than five percent. Additionally, when viewing the member from the first direction, the difference between a color reflectance of the member at the substantially opaque region and at the sensor opening region is less than 5 delta C* units. A sensor disposed in a second direction of the sensor opening region of the member is operable to receive light through the member at the sensor opening region. The second direction is opposite the first direction.
