A more simple explanation is how an artificial light source shifts the location of eight specified colors on a version of the C.I.E. color space as compared to the same colors lighted by a reference source of the same Color Temperature. If there is no change in appearance, the light source is given a CRI of 100 by definition.
A perfect light source would have a CRI Ra of 100 for a given color temperature (CCT). Most indoor LED sources have a CRI Ra around 80. An 80 CRI LED might only have an R9 of 20 or even much
Here’s a simple CRI rating guide that can affect the lighting you choose for your bathroom. 0-55 — Poor; 60-85 — Good (best for bathroom lighting) 90-100 — Excellent; A CRI rating of 80 renders colors as they appear in natural light.

The CRI value, on a scale of 0 to 100, is used to compare one LED light to another. If one has a CRI of 80, which most LED bulbs currently do, and you see another one has a CRI of 89, then you know that using the latter will show more saturated colors than the former. When an LED light has a CRI of over 90, it's classified as a high CRI LED.
LEDs bulbs can produce a wider range of colors, from more yellow warm (2700K) to more blue cool tones (6500K). The lower the Kelvin scale value, the warmer and more yellow the light appears, while the higher the Kelvin value, color appearance is a blue, cool light. Most ceiling fans and light fixtures will have a 3000K rating as this is typical
