The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.
