Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.
Chromatic adaptation is a prime example for the case that two different stimuli with thereby different XYZ tristimulus values create an identical color appearance. If the color temperature of the illuminating light source changes, so do the spectral power distribution and thereby the XYZ tristimulus values of the light reflected from the white ...
Color theory, or more specifically traditional color theory, is a historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. [1]
The chromatic adaptation matrix in the diagonal von Kries transform method, however, operates on tristimulus values in the LMS color space. Since colors in most colorspaces can be transformed to the XYZ color space, only one additional transformation matrix is required for any color space to be adapted chromatically: to transform colors from ...
In color science, the white point of an illuminant or of a display is a neutral reference characterized by a chromaticity; all other chromaticities may be defined in relation to this reference using polar coordinates.
In color science, chromatic adaptation is the estimation of the representation of an object under a different light source from the one in which it was recorded. A common application is to find a chromatic adaptation transform (CAT) that will make the recording of a neutral object appear neutral ( color balance ), while keeping other colors ...
Log-log plot of spatial contrast sensitivity functions for luminance and chromatic contrast [improve caption] The neurological conversion of color from LMS color space to the opponent process is believed to take place mostly in the lateral geniculate nucleus (LGN) of the thalamus, though it may also take place in the retina bipolar cells.
Light spectrum, from Theory of Colours – Goethe observed that colour arises at the edges, and the spectrum occurs where these coloured edges overlap.. Theory of Colours (German: Zur Farbenlehre) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans.
