ABSTRACT:
The present invention provides a color code for displaying information using an arranged combination of a plurality of color phase marks wherein the color code includes a plurality of column marks arranged at uniform intervals, and a plurality of color phase marks arranged around the periphery of each of the aforementioned plurality of column marks using each of the plurality of column marks as a reference. In order to read out the color code, initially, a column mark is read out, and after its arrangement has been determined, the color phase marks arranged at predetermined positions around the periphery of the column mark are read out. The codes, i.e. data, are then obtained by referencing combinations of color phases of the color phase marks read out with a predetermined color code table.
