Color Rendering (Ra)

 

 

  • Color rendering, expressed as a rating from 0 to 100 on the Color Rendering Index (CRI), describes how a light source makes the color of an object appear to human eyes and how well subtle variations in color shades are revealed.
  • Ra can be found in the specifications of the luminaire. The higher the number the less color distortion.

We don’t measure Ra on site but we can observe and experience it: 

Look at the skin of your hands.How do they look? Natural, or brownish? Yellowish? How do you perceive the colors around you?
