UNIFIED PROFILES OF SPECTRAL DATA

What is it?

A method to map spectral data on common color expressions. Unified profiles represent radiometric data, therefore neither information about cone response or luminous efficiency is required.

How does it work?

The profiles are generated from data describing the spectral distribution in the range between 443nm and 656nm. The four defined wavelength bands align with the four unique hues of the Natural Color System (NCS). The representation is similar to one known from graphic equalizers. The naming of the wavelength bands indicates color impressions that most likely appear when these signals are interpreted. Unified profiles can be applied to describe light sources, surface reflection characteristics or light that is reflected off a surface or transmitted through a material.

Here is a small but growing database of cases where unified profiles are applied.
