High CRI brings out true colors

A red apple appears red because it reflects red wavelengths, but absorbs others.

But not all white light sources have the same amount of red wavelength light.

As a result, under different light sources, a red apple can reflect different amounts of red light, changing its appearance.

The Color Rendering Index (CRI) measures the ability of a light source to bring out the true colors of an object. Without a high CRI light source, objects can appear faded, dull or inaccurate.
