Colour rendering

Correlation between the natural colour of an object and how it appears under a given light source

Colour rendering

Colour rendering relates to the way objects appear under a given light source. The measure is called the "colour rendering index" or CRI.
A low CRI indicates that objects may appear unnatural under the source, while a light with a high CRI rating will allow an object's colours to appear more natural.
The maximum value of the CRI of a source is equal to 100. The higher the value, the better the colour rendering is.
Light sources providing a CRI over 80 are considered as excellent for colour recognition.
