1. A method for providing a metallic surface with a coating by applying one or more layers of one or more metal-containing slips to the surface, wherein at least one of the one or more slips comprises metal-based particles, is gray and further comprises at least one coloring and/or color-imparting substance which has no influence on the properties of the completed coating and/or can be decomposed by thermal treatment, and the local thickness of an applied slip layer is determined on the basis of a local color intensity of the layer.
