ColorCode is a two-dimensional "bar code" that uses colors to encode data. It has been referred to as a "3D bar code" because it has color depth as its third dimension. (There have even been references to "4D bar codes" consisting of something like a ColorCode being displayed on a monitor or phone display in a manner where the colors keep changing, adding time as a fourth dimension.)
ColorCode is a proprietary system (covered by US patents [1], [2], and [3]) which was developed in Korea and is used mostly in Asia.
ColorCode bar codes might not actually look like bar codes; it is possible to "hide" a ColorCode in an image or colored text piece, as long as the proper pattern of colors is present.
