'''False colors''' and '''pseudo colors''' respectively refers to a group of [[color]] [[Signal processing|rendering methods]] used to display images in colors which were recorded in the [[visible spectrum|visible]] or non-visible parts of the [[electromagnetic spectrum]]. A '''false-color image''' is an image that depicts an object in [[color]]s that differ from those a [[photograph]] (a '''true-color image''') would show. In this image, colors have been assigned to three different [[wavelengths]] that human eyes cannot normally see.

In addition, variants of ''false colors'' such as '''pseudocolors''', '''density slicing''', and '''choropleths''' are used for [[information visualization]] of either data gathered by a single grayscale channel or data not depicting parts of the electromagnetic spectrum (e.g. elevation in relief maps or tissue types in [[magnetic resonance imaging]]).
