Colour replacement is defined as the experience of a person's entire visual field or specific objects and sections within it becoming replaced with an alternative colour which differs from its original appearance. For example, the person's vision could become tinted purple, the green leaves of a tree could become red, or a black car could become white.
Although similar, this component differs from colour shifting as it is a static change in colour which remains still and semi-permanent as opposed to constantly cycling between various hues, tints and shades.
Colour replacement is often accompanied by other coinciding effects such as color enhancement and colour shifting. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
