Not sure why this is downvoted. It's simple color theory, and the whole reason the CRI measure exists.
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.

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