A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.

An external yellow photographic filter is used (Wratten #12 or equivalent) to block the blue and violet wavelengths, which results in a false-color image by translating or remapping the captured spectrum (from green through infrared) to the visible spectrum: Infrared wavelengths are mapped to the red color, even though the infrared wavelengths ...
A VNIR image of the Ghadamis River in Libya.This is a false-color composite image made using near-infrared, green, and blue wavelengths. The visible and near-infrared (VNIR) portion of the electromagnetic spectrum has wavelengths between approximately 400 and 1100 nanometers (nm). [1]
Color infrared aerial photographs are captured using false color film which changes the original color of different features into "false color". [2] [5] For example, grasslands and forests which are green in nature have a red color. [2] But some artificial objects which are covered in green may have a blue color. [2]
A false-color image of two people taken in long-wavelength infrared (body-temperature thermal) radiation This pseudocolor infrared space telescope image has blue, green, and red corresponding to wavelengths of 3.4, 4.6, and 12 μm, respectively.
A false color photograph with ultraviolet radiation (335-365nm) mapped to the blue channel, green light (500-600nm) to the green channel and infrared radiation (720-850nm) to the red channel. Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ...
Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
False-color image – Methods of visualizing information by translating to colors, an image that depicts an object in colors that differ from those that a visible-colors-only photograph would show. Middle gray – Shade of the color gray used to adjust photographs to match perceptual brightness, as opposed to absolute brightness as measured by ...
