chromaticity 

Colour quality of a colour stimulus definable by its chromaticity coordinates, or by its dominant (or complementary) wavelength and its purity taken together (CIE). See saturation; dominant wavelength.

It is also obvious that, for the dark skin colour, for all the ISO speeds, with shooting and editing came to the small change of chromaticity, while the changes are slightly higher for the light skin colour (Tables 1, 2, 3 and 4).
Shape and/or size (Experiment 1) or shape and/or chromaticity (Experiments 2 and 3) of the objects could change between their first and second exposures.
The spectral distribution and chromaticity coordinates of a number of LEDs have been measured (2).
The CS-150 with the 1A measuring angle of its predecessor together with the new CS-160 which has a smaller measuring angle of 1/3A enable measurements of the luminance and chromaticity of small light-emitting surfaces, such as micro displays or of small, sharply defined areas of distant light sources such as traffic or street lights.
21) The results were then compared with RG thresholds measured with the Colour Discrimination and Diagnosis (CAD) test; this test is performed on a colour calibrated visual display unit and presents stimuli of precise chromaticity and saturation as moving targets within a dynamic background of neutral grey dots that mask luminance contrast.
In addition to a higher CRI, the California Quality Spec also requires a tighter chromaticity than ENERGY STAR.
LM-79 describes how to characterize LED luminaires and integrated LED lamps in five areas, including total luminous flux, total input power, luminous intensity distribution, and chromaticity [IESNA 2008a].
Rudolf Leopold: Intense chromaticity as an allegory of youth
They have outstanding lightfastness, but have poor color strength, high density, and lower intensity and chromaticity than organics.
The first chapter is devoted to fundamentals of light-emitting diodes, the perception of vision by the human eye, methods used in conjunction with the chromaticity diagram, and associated international standards in terms of color temperatures and color rendering index.
Pulse-width modulation can be readily achieved in vehicle lighting systems and has an advantage over filament based sources in that dimming LEDs in this way does not appreciably shift the chromaticity or color appearance, whereas dimming filament sources will result in increased relative long-wavelength output and a yellower color appearance.
