The data of the color temperature refers only to the color of light, and not its spectral composition , which is essential for color reproduction. Thus, two light sources can have properties very similar colors and both have a very different color.
The color rendering index (CRI or Ra) has the ability to reproduce the colors of objects illuminated by a light source. The CRI provides an indication of the ability of the light source to reproduce the colors in relation to the reproduction light provided by a standard reference standard.
