Colour requirements for manufacture and retail are
complex and diverse. To ensure product colour, several
types of light source are used (e.g. Artificial Daylight
and a Point of Sale Light). Multiple light sources are
also necessary to reveal colour inconsistencies and
metamerism.
For many products, it is critical to ensure components
are assessed under the same illuminants, using defined
procedures, in a controlled viewing environment, by
everyone in the supply chain.
This ensures standardised and repeatable colour
assessment.
To ensure controlled standardised light, two factors require consideration...
1. COLOUR TEMPERATURE - Kelvin. (K) 2. COLOUR RENDERING INDEX (CRI)
Colour temperature describes the colour appearance A numerical system that measures how well colours
of the light and can vary along with its spectral power are rendered by a lamp in comparison to a reference
distribution. light source.
Applies to any light source that deviates from the CRI is measured on an index from 0 - 100, with 100
plankian locus. being an exact match, low values indicate poor colour
Lower colour temperatures appear warmer, such as rendering. VeriVide D65 has a CRI rating of 98, this
Illuminant 2856K and 3000K. Lamps with a higher colour shows colours more accurately than a CWF with a CRI
temperature look cooler or bluer, like VeriVide 6500K and rating of 62.
7500K. This rating method is recognised by the Illuminating
Engineering Society (IES) and the Commission
International de L’Eclairage (CIE).
