The vast array of colours we see is known as visible light, and only represented by a tiny band within the electromagnetic spectrum. The visible light spectrum is between the wavelengths of ~380nm (violet) to ~740nm (deep red) and commonly referred to as the rainbow.

Indoors, what we perceive as an object’s colour is strongly correlated to the qualities of the artificial light source illuminating the object. A term commonly used within the lighting industry is colour rendering index (CRI) which is a metric used to analyse a light sources colour reproduction qualities. However, the CRI metric does have a few limitations.

TM-30 was first introduced in 2015 to overcome the limitations in CRI. The purpose of TM-30 is to provide a more accurate measure of a light source to provide designers the data to enhance all spaces. TM-30 is quickly gaining traction.

In this white paper, you will:

  • Learn about the four fundamentals of colour in lighting
  • Understand the science of colour perception and interpretation
  • Learn how TM-30 compares to the existing CRI standard
