[[File:Anaglyph glasses.png|thumb|The archetypal 3D glasses, with modern red and cyan color filters, similar to the red/green and red/blue lenses used to view early anaglyph films]]

In an anaglyph, two images are [[superimposed]] in an [[additive color|additive light]] setting through two filters, one red and one cyan.  In a [[subtractive color|subtractive light]] setting, the two images are printed in the same [[complementary color]]s on white paper.  Glasses with colored filters in each eye separate the appropriate image by canceling the filter color out and rendering the complementary color black. A compensating technique, commonly known as Anachrome, uses a slightly more transparent cyan filter in the patented glasses associated with the technique. Process reconfigures the typical anaglyph image to have less [[parallax]].

An alternative to the usual red and cyan filter system of anaglyph is [[ColorCode 3-D]], a patented anaglyph system which was invented in order to present an anaglyph image in conjunction with the NTSC television standard, in which the red channel is often compromised.  ColorCode uses the complementary colors of yellow and dark blue on-screen, and the colors of the glasses' lenses are amber and dark blue.
