Colorimetry

Spectrocolorimeters and spectrophotometers, spectrodensitometers, colorimeters, color temperature and chromaticity coordinates meters, color rendering index meters

Modern science defines  color  as a sensation that occurs in a person’s organ of vision when exposed to light. Of course, the perception of any color primarily depends on the individual characteristics of each person, but excessive or insufficient brightness and other changes in characteristics can lead to a distortion of perception. Therefore, the measurement of the color characteristics of light sources must be carried out everywhere. The resulting color can be expressed in three color coordinates or two chromaticity and lightness coordinates. Also, color can be expressed through lightness, purity and hue. Color and  chromaticity  coordinates are calculated based on the spectrophotometric characteristics of colored bodies or using light measuring devices – spectrophotometers, spectrocolorimeters, colorimeters, comparators and using color atlases. The so-called correlated color temperature is used to evaluate white light  . This indicator reflects the perception of white. Color deviations that can be distinguished even at the same color temperature are tolerated by the standard color temperature definition. The psychological aspect of the effect of color temperature on a person should not be underestimated either. This indicator significantly affects the perception of space and is able to change the appearance of objects.
