This short course has provided an insight into the complexity of describing colour and the 3-dimentional nature of this process. There are a number of reasons why colour communication is very difficult, for example:

1. Perceptions and interpretations of colour are very subjective.
2. Physiological and psychological factors can influence colour perception.
3. Perception is altered depending on surroundings, particularly lighting conditions and adjacent colours.

A set of international standards is, therefore, required in order to ensure colour constancy in any given product anywhere in the World. This is achieved by use of the Munsell System (originating in 1905) which sets numerical values to the terms hue, value and chroma.

During the course you have looked at 3 different fibres and the dyeing process of choice for each. Colour constancy of a product relies on using the correct fibre/dye combination. This will not only give you a better quality-controlled product, but it will reduce the negative environmental impact, both in production and end use, as summarised in the linked diagram:
