Chromadepth is a patented system from the company Chromatek (a subsidiary of American Paper Optics since 2002) that produces a stereoscopic effect based upon differences in the diffraction of color through a special prism-like holographic film. Chromadepth glasses purposely exacerbate chromatic aberration (the failure of a lens to focus all colors to the same convergence point) and give the illusion of colors taking up different positions in space, with red being in front, and blue being in back.

The effect works particularly well with the sky, sea or grass as a background, and redder objects in the foreground. From front to back the scheme follows the visible light spectrum, from red to orange, yellow, green and blue. This means any color is associated in a fixed fashion with a certain depth when viewing. As a result, ChromaDepth works best with artificially produced or enhanced pictures, since the color indicates the depth.
