Figure 2: The Berlin-Kay Partial Ordering

in the retina before any subsequent visual information processing occurs.
The principle of minimum duplication is a minimality requirement in the same
way as Ockam’s razor (requiring the minimal explanation for scientific data) in
the philosophy of science, however ultimately it might be possible to formulate
it as a minimality requirement like the principle of least action in physics.
2 Name Strategy in Colour Perception
2.1 Berlin-Kay Colour Ordering
The perception of colour often involves the deployment of a colour name strat-
egy. The effect of this is to alter the way the colour is perceived. The five
principles of colour perception have been given by Brown (1976) [4]:
1. The communicability of a referent in an array and for a particular com-
munity is very closely related to the memorability of that referent in the
same array and for members of the same community.
2. In the total domain of colour there are eleven small focal areas in which are
found the best instances of the colour categories named in any particular
language. The focal areas are human universals, but languages differ in
the number of basic colour terms that they have; they vary from two to
eleven.
3. Colour terms appear to evolve in a language according to the Berlin-Kay
(1969) [2] universal partial ordering:
4. Focal colours are more memorable, easier to recognize, than any other
colours, whether the subjects speak a language having a name for the
colour or not.
