Abstract
An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a ΔE of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.
