CRI Explained: When Color Accuracy Actually Matters
Two lights can be the same brightness and color temperature yet make the same object look completely different. The reason is CRI. For paint, print, food, and retail, it is a make-or-break spec. This guide explains it.
CRI (Color Rendering Index) rates how accurately a light shows color versus natural daylight, on a scale to 100. 80+ is fine for general spaces; 90+ is needed for color-critical work like paint matching and inspection.
What CRI Measures
CRI compares how colors look under a light to how they look in daylight. A high CRI light reveals true color; a low CRI light can wash out or shift hues, even at the same brightness and Kelvin.
When You Need High CRI
- 90+: auto body paint matching, showrooms, print, inspection, food display.
- 80+: general warehouse, shop, and office areas.
CRI and Color Temperature Together
Pair high CRI with the right color temperature. For color work, 5000K at 90+ CRI is the standard combination.
