Color reproduction is an aspect of
color science concerned with producing light spectra that evoke a desired
color
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are assoc ...
, either through
additive (light emitting) or
subtractive (surface color) models. It converts physical correlates of color perception (
CIE 1931 XYZ color space tristimulus values and related quantities) into light spectra that can be experienced by observers. In this way, it is the opposite of
colorimetry
Colorimetry is "the science and technology used to quantify and describe physically the human color perception".
It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color ...

It is concerned with the faithful reproduction of a color in one medium, with a color in another, so it is a central concept in
color management and relies heavily on
color calibration. For example, food packaging must be able to faithfully reproduce the colors of the foods therein in order to appeal to a customer.
This involves proper color calibration of at least four devices:
* Lighting, which must have a high
color rendering index and not give a
color cast to the object.
* Camera, which
measures the reflected spectrum of the object and converts to a trichromatic color space (e.g.
RGB).
* Screen, which reproduces color so a designer can proof the captured image and make color corrections as necessary.
* Printer, which reproduces the final color on paper.
