Infants as young as 12 weeks old exhibit color preferences. [2] Generally, children prefer the colors red/pink and blue, and cool colors are preferred over warm colors. Color perception of children 3–5 years of age is an indicator of their developmental stage. Color preferences tend to change as people age. [3]
Matching was performed across many participants in incremental steps along the range of test stimulus wavelengths (380 nm to 780 nm) to ultimately yield the color matching functions: ¯ (), ¯ and ¯ that represent the relative intensities of red, green, and blue light to match each wavelength ().
A classic example is the automobile industry: the colorants used for interior fabrics, plastics and paints may be chosen to provide a good color match under a cool white fluorescent source, but the matches can disappear under different light sources (e.g. daylight or tungsten source). Furthermore, because of the differences in colorants ...
Grassmann's laws describe empirical results about how the perception of mixtures of colored lights (i.e., lights that co-stimulate the same area on the retina) composed of different spectral power distributions can be algebraically related to one another in a color matching context.
The above development has the advantage of basing the new X F Y F Z F color matching functions on the physiologically-based LMS cone response functions. In addition, it offers a one-to-one relationship between the LMS chromaticity coordinates and the new X F Y F Z F chromaticity coordinates, which was not the case for the CIE 1931 color ...

For the example color of S 2030-Y90R, the saturation is calculated as = / = / = / = NCS lightness (v) is a color's perceptual characteristic to contain more of the achromatic elementary colors black or white than another color. NCS lightness values varies from 0 for the elementary color black (S) to 1 for the elementary color white (W).
