Chromatic aberration, also known as chromatic distortion and colour fringing, is when the colours reflected off of an object's surface become distinctly split into three overlapping offset layers. These split layers can potentially be any colour, but are most commonly reported to be red, green, and blue. This distortion results in the surrounding environment looking somewhat similar to how things look when a person is wearing red blue anaglyph 3D glasses.
Chromatic aberration is often accompanied by other coinciding effects such as colour enhancement and colour shifting. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
