Warp knit denim fabrics wherein differentially colored or colorable yarn sets or groups are knit together in a fabric having a dominant, typically darker, color forming a background wherein flecks of a less dominant, typically lighter, color are present substantially uniformly throughout the surface of the fabric, thereby giving a fabric whose visual appearance is similar to woven denim fabrics, but which possesses superior fabric qualities. After knitting, the differentially colorable yarn sets may be dyed to selectively color one or more of the yarn sets. The denim effect may be enhanced by sanding or napping the denim surface of the fabric to abrade and/or break the dominant color yarns and blend the lighter color therewith. The fabric may be thereafter calendered, and finished in conventional manner.
