fargeimeter

The fargeimeter is a proposed or hypothetical instrument designed to quantify perceptual aspects of color by integrating physical measurements with models of human vision. In concept, it would produce a perceptual color profile that reflects hue, brightness, and saturation within a standardized perceptual space.

It would combine spectrophotometric measurements of a light source or sample with psychophysical data to translate spectral power distribution into coordinates in a perceptual color space such as CIE Lab or a perceptual model like CIECAM02. Calibration would rely on observer-based references, and the device would output a fargeimetric distance or coordinates that represent perceptual differences or similarities between colors.

If realized, the device could support color quality control in displays and printing, color-critical imaging, art conservation, and research into human color perception, particularly where perceptual equivalence matters more than purely spectral similarity.

The term is not part of standard colorimetric practice and appears mainly in speculative or theoretical discussions. There is no widely recognized instrument by this name in mainstream literature. The etymology reflects a coined blend of a pseudo-root for color with the suffix -meter.
