What is CRI (Color Rendering Index)?

The Color Rendering Index, commonly known as CRI, is a quantitative metric used to assess a light source’s ability to accurately reveal objects’ colors compared to a natural light source. The CRI value, presented on a scale ranging from 0 to 100, represents the light source’s faithfulness in accurately reproducing colors. A CRI rating of 100 signifies that the light source accurately renders colors like natural daylight, while lower values indicate a decrease in color accuracy.

Indeed, it is well understood that each light source possesses its unique characteristics. When subjected to various artificial lights such as LED lighting, incandescent bulbs, fluorescent tubes, or halogen sources, an object may exhibit subtle variations in color reflection.

The closer a light source resembles natural daylight, the more accurately it will render colors on objects. For instance, a red dress may not appear as vibrant under a fluorescent lamp compared to natural sunlight. Understanding this concept empowers you to be mindful of the luminaire you choose, ensuring it can effectively showcase your space and its true colors.

The subsequent illustration will aid in comprehending the impact of an artificial light source’s color-rendering capability on what we perceive. Notably, the color appearance of an object experiences a considerable decline when observed under a low CRI LED light.

color rendering capability

Using the “Color Rendering Index-CRI” or “CIE Ra” – an international standard for assessing color rendering – scientists have devised a method to quantify this phenomenon. The general rule is straightforward: the higher the CRI value, the more superior the perceived color scheme.

It is essential not to confuse this with the term “Correlated Color Temperature,” which primarily describes the hue of light. However, it is worth noting that color temperatures influence the CRI of a luminaire.

Where Will You See?

The lamp package typically displays the CRI value from 0 to 100. Higher CRI values are generally considered better, but the ideal value depends on the specific application. While a mid-range CRI might be suitable for a living area, it may not meet the requirements of an art gallery, where more accurate color representation is necessary.

The value is obtained from a Color Rendering Index Chart and is relatively self-explanatory when observed.
