Abstract
A barcode symbol having an encoded symbology is provided with color or shades of gray to add additional information at the time of printing. The color or shades of gray provides the current barcode symbology with a third dimension of information. The color or shades of gray can encode information over a specific one-dimensional or two-dimensional symbology. White spaces can be replaced with colors or shades of gray to add coded information to the standard one-dimensional and two-dimensional codes. The number of colors and how they are distributed or arranged can provide the basic backbone of information. A barcode reader that can detect the different color spectrums, can be employed to decode the information. Furthermore, color is not limited to white spaces, but can be implemented into black spaces. Additionally, colored background information can provide additional information to the current symbology.
