Unfortunately, CRI or Ra, agreed upon in 1974, is more of a "how well do eight pastels look when illuminated by this light spectrum?"

CIE's R96a (1999) remains stuck in a disagreement between scientists and manufacturers. This means that lights currently specified with a CRI value are advertising an inaccurate measure of their ability to reveal the color of objects.

Knowing even only the 1974 CRI of a light source is much better than knowing nothing about it.

A very good CRI does not guarantee a very good color reproduction, but a poor CRI guarantees a bad color reproduction.

I've seen many very new comments start out grey until someone votes for it. No idea why that is.
