Official color match critique standard. Record the 12 digit number printed on the front of the card proceeded by the selected color number(s) of 1 to 48. The STD Cards are designed to provide a repeatable and accurate Standard Color Matched Selection of colors to visually compare and record what is observed. This is accomplished, not by trying to guess what color to call it, but by the number representing the color. Pick the color number closest to the bruise present. More than one color might be present from the center of the bruise to the outside perimeter. Record colors and locations accordingly. Holding a STD Card next to the bruise while photographing provides conclusive evidence.
