👉 Adapt the color temperature room by room allows for the optimization of both visual comfort and the use of each space.

Neglecting the color rendering index (CRI)

The color rendering index (CRI) measures a light source's ability to accurately reproduce colors. A CRI that is too low can distort the perception of hues, making colors appear dull or artificial.
