CRI is the abbreviation used for color rendering index. It is a measure of the light source’s ability to show the object’s “real” or “natural” colors in a scale from 1 to 100. The method of measure established by the International Commission on Illumination (CIE), evaluates the quality of 8 standard color samples (R1 to R8) that are compared to a correlated color temperature (CCT) and the variation of the difference determines de CRI.
But why is CRI important? Because it can make a great impact on the environment and in some commercial cases, it can also increase the attraction to a product and potentially translate into generating more sales. Here are a few images to illustrate this: (Bad CRI on the Left, Good CRI on the right)
So, if you’re looking into designing a new space, or remodeling an existing one, make sure your lighting is as efficient as possible so that your signature design elements are as visually aesthetic as possible!
