Color chips or color samples from a plastic pellet manufacturer that enables customers to evaluate the color range as molded objects to see final effects. A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or ...
RAL is a colour management system used in Europe that is created and administered by the German RAL gGmbH [1] (RAL non-profit LLC), which is a subsidiary of the German RAL Institute .

Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2] For this reason it is essential to use multiple different tests to show all adulterants.
The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured reflectance spectra, it is possible to derive CIELAB coordinates for Illuminants D 65 and D 50 and coordinates in sRGB ( D 65 ).
Color analysis (American English; colour analysis in Commonwealth English), also known as personal color analysis (PCA), seasonal color analysis, or skin-tone matching, is a term often used within the cosmetics and fashion industry to describe a method of determining the colors of clothing and cosmetics that harmonize with the appearance of a person's skin complexion, eye color, and hair color ...
Matching colors or (in British English) colours usually refers to complementary colors, pairs or triplets of colors that harmonize well together. Matching colors may also refer to: Color management , the matching of color representations across various electronic devices.
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose chroma) by producing a grayscale color like white or black. [1] [better source needed] When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors".
