Abstract: A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.
