Värviedastusindeks, often abbreviated as CRI or Ra, is a quantitative measure of a light source's ability to reveal the colors of various objects faithfully compared to an ideal or natural light source. It is a system developed by the International Commission on Illumination (CIE). The index is a value between 0 and 100, where a CRI of 100 indicates that the light source renders colors perfectly.
Lower CRI values suggest that the light source may distort the colors of objects, making them appear
The CRI is calculated using a series of standardized color samples. The accuracy of color rendition is
