Color Rendering Index (CRI)

Colour Rendering Index (CRI) is the ability of transmitted daylight through the glazing to portray a variety of colours compared to those seen under daylight without the glazing. Scale is 1 - 100.

For instance, a low CRI causes colours to appear washed out, while a high CRI causes colours to appear vibrant and natural.

In commercial glass, CRI indicates the effect the specific glass configuration has on the appearance of objects viewed through the glass.
