A color code system for encoding information on products and other substrates. The color code is printed by a color printer using single intensity colors in specific shapes aligned side by side successively. The code is predetermined. The code can be read by a video device and decode by a computer.

A color code system for encoding information on products and other substrates. The color code is printed by a color printer using single intensity colors in specific shapes aligned side by side successively. The code is predetermined. The code can be read by a video device and decode by a computer. The present invention allows for densely packed encoded information in a small space that can be cheaply and easily read and decoded.
