Colorimetry
Part of speech: noun
Definitions
- The measurement and analysis of color intensity through specific scientific methods allows for the evaluation of color properties across various substances
- A systematic approach to quantifying color by examining light absorption enables the assessment of color characteristics in different contexts

Etymology: Colorimetry is a compound built from two parts with long separate histories. The first, "color," came into English through Anglo-Norman "colur" from Latin "color," which probably traces back to the Proto-Italic "kelōs" and a much older Indo-European root meaning something like "to cover" or "to conceal," a hint that color was once thought of as a surface covering. The second element, "-metry," reaches English from Old French "-métrie," which descends from the Ancient Greek "-metría," a suffix meaning "a measuring," and the Greek "métron" for "measure." Its path shows that the word's measuring element is one of the oldest in the family of scientific terms. Put together, "colorimetry" means the measurement of color, which is the sense the word carries in optics and industry: quantifying how a sample absorbs and reflects light so that its color can be specified numerically. The combining form "-metry" appears in many other terms, such as "geometry" and "thermometry," which is why the coinage feels so familiar even though the specific compound is more recent than its parts.
Synonyms: color measurement, color analysis, color evaluation
