Color Rendering Index (CRI)

The ability of transmitted daylight through the glazing to portray a variety of colors compared to those seen under daylight without the glazing. Scale is 1 – 100.

For instance, a low CRI causes colors to appear washed out, while a high CRI causes colors 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.
