Metamerism is one of the major factors that contribute in creating colour discrepancies in the production process. It is a natural phenomenon of difference in the appearance of the colour of a material in different lighting conditions.

Be it any industry, it is a major reason for concern. In a production house, due to the difference in lighting conditions of the material supplier, production line, packaging line, etc. there appears colour difference.

Take the example of automotive industry, every part is manufactured in different plants. When they are assembled together, any slightest of colour difference would lead to rejection. Therefore, matching of the master with the sample under ideal lighting condition is very important.

  • Illuminant Metamerismoccurs due to the difference in lighting conditions. It is experienced by the same observer when the lighting conditions change.
  • Observer Metamerism is experienced by different observers when the lighting conditions remain unchanged. This usually happens due to the difference in lighting conditions.
  • Geometric Metamerism is experienced when the colour of an object appears differently due to its placement. Shadow is a very common reason for this. Therefore, an object that is to be observed should be kept at an angle of 45°.
