Color analysis can be conducted by-eye, usually matching specimen color with reference charts. This methodology has been used extensively in soil analysis, often using the Munsell color system as the reference. [1] [2] While this is a traditionally used method, it is considerably subjective, relying on the ability of the naked eye to match colors.

Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
The International Colour Association (Association Internationale de la Couleur (AIC), or Internationale Vereinigung für die Farbe) is a learned society whose aims are to encourage research in all aspects of colour, to disseminate the knowledge gained from this research, and to promote its application to the solution of problems in the fields of science, art, design and industry on an ...
APHA color, also referred to as the Hazen scale, and more appropriately as the Platinum Cobalt(Pt/Co) scale, [1] is a color standard named for the American Public Health Association and defined by ASTM D1209. [2] It was originally intended to describe the color of waste water, but its usage has expanded to include other industrial applications ...
CIELAB D50 is available in ICC profiles as a profile connection space named "Lab color space". [2] CIELAB (any white point) is a supported color space in TIFF image files. [17] CIELAB (any white point) is available in PDF documents, where it is called the "Lab color space". [18] [19] CIELAB is an option in Digital Color Meter on macOS described ...
A uniform color space (UCS) is a color model that seeks to make the color-making attributes perceptually uniform, i.e. identical spatial distance between two colors equals identical amount of perceived color difference. A CAM under a fixed viewing condition results in a UCS; a UCS with a modeling of variable viewing conditions results in a CAM.
