ICI Colour Palette October 12, 2008

ICI Paints (now Akzo Nobel) has its own proprietory colour notation for the colours in its colour palette fanbook. Colours present in this range can be produced by ICI’s Dulux Colour Solutions Tinting System. The system can produce the various types of Dulux paints - Pentalite, Pearl Glo, Gloss Finish and Weathershield.
The notation used by Dulux, though different in structure, is similar to the NCS notation (see post) in its use of hue, chromaticness, and "blackness". An example of the Dulux notation is shown below:
The colour notation indicates the degree of hueness, the LRV (Light Reflectance Value), and the chroma value of the colour. 30 BG therefore denotes a colour that is between Blue and Green on a scale of 100. A number higher than 50 means that the colour is closer to Blue while a number less than 50 means that it is closer to Green.
The LRV also ranges between 0 and 100. The bigger the number, the lighter the colour. This number is somewhat similar to the first 2 digits in the NCS notation, which indicates the degree of "blackness".
The last part of the notation is the ‘Chroma’. It is a number between 0 and 999. The chroma of a colour makes the colour either intense or subtle. Therefore, the higher the number, the more intense the colour becomes.
The Dulux colour notation system is yet another type used for specifying colours. I suppose ICI adopted a proprietary system to cater to its strength in colours. Unfortunately, this system, being proprietary, is unlikely to be adopted as industry standard for specification of colours.
