Colour

The human eye is capable of differentiating several million colours, despite this subjective visual evaluation, when used for quality control purposes, is no longer preferred as it suffers from a lack of real quantifiable data and inconsistent documentation.

Since the early 1930’s many scientific measuring techniques have been developed by National Standards Organisations, among them the CIE (International Committee of Light), based on a logical numeric scaling where physical parameters and calculations have been clearly defined, universally accepted and adopted. As a result, many methods are today perfectly proven, and governed by major standards such as ASTM, BS, DIN, or ISO etc.
