Without colors, everything is just boring. The vividness of colors makes our life bright and vibrant. Sunlight has so far been considered to accurately render colors. But, what happens to indoor lights? Well, have you ever observed how the favorite paint on your wall looks different at night than how it looks in the morning? That is because of your indoor lamps. Most indoor lamps struggle to keep-up the color rendering index (CRI), like that of the Sun.
What is CRI?
A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. It is measured on a scale from 1 to 100, with 100 representing daylight. CRI was devised by the International Commission on Illumination (CIE) to evaluate how effectively light sources represent color across 8 colors, from R1 to R8.
Why is CRI important?
A CRI value of 80+ will effectively portray colors and finishes. When the most accurate color rendering is essential, 90+ CRI values are recommended. With a high CRI lighting, colors pop and textures stand out.
Take, for example, the bowl of food below. Under an 80+ CRI, all the colors are visible. But with a 90+ CRI, the object has more depth and luster in its texture.
