Värvimõõtmised, often translated as color measurements, refers to the quantitative assessment of color. This process involves using instruments to objectively determine the color characteristics of an object or material. Instead of relying on subjective visual perception, color measurements provide precise data that can be used for comparison, quality control, and color matching.

The fundamental principle behind color measurement is the tristimulus color system. This system represents color using three values, typically derived from how the human eye perceives red, green, and blue light. Instruments like spectrophotometers or colorimeters capture the spectral reflectance or transmittance of a sample across the visible spectrum. This spectral data is then mathematically converted into tristimulus values, such as CIE XYZ or CIE L*a*b*, which are standard ways to numerically describe color.

These measurements are crucial in various industries. In manufacturing, they ensure consistency in product color, from paint and textiles to plastics and food. For example, a paint manufacturer will use color measurements to ensure that a batch of red paint matches the specified standard. In printing, color measurements help reproduce images accurately on different media. They are also vital in scientific research, art conservation, and the development of new color technologies. The objectivity and repeatability of color measurements make them an indispensable tool for anyone concerned with precise color control and communication.
