Abstract
A coating in accordance with the invention has a substantially crystalline first layer with a substantially crystalline second layer provided over the first layer. A breaker layer is provided between the first and second layers and is configured to prevent or at least reduce epitaxial growth of the second layer on the first layer. A color suppression layer may be provided below the first layer. The coating can be provided on a substrate to make a coated article. A method of coating a substrate includes depositing a substantially crystalline first layer over at least a portion of the substrate and depositing a breaker layer over the first layer. The breaker layer is configured to prevent or at least reduce epitaxial growth of a subsequently deposited layer on the first layer.
