The sheeting and the granular material consist of cross-linkable, elastomeric materials, the granular material comprising particles which have at least two subregions dyed differently from each other and from the sheeting. The quantity and color of the fractions of each component as selected so that the mixed color resulting from an homogeneous intermixing of all the components contained in the floor covering agrees with the first color.
