2 A DICTIONARY OF COLOUR
Single subject dictionaries are grossly under-utilised, particularly as an introduction
to the subject. All too frequently this powerful resource is dusted down and used
in a one-off search for a definition after which it is immediately returned to its
place on the shelf. A good dictionary should be regarded as a foreign land calling
out for exploration and to which each visit is a journey of discovery, each dictionary
entry drawing one onto the next, sucking in the reader and making it difficult for
him to leave. I hope that this work might serve just such a purpose and will attract
visitors to stay and explore rather than merely to pay a flying visit.
I would hope that this Dictionary, touching on the whole spectrum of colour
relevance, will serve as an invaluable resource for art students and students of
colour, although it is neither a technical exposition of the many facets of colour
nor a guide on how to use colour.
Much of what colour has to offer might appear to some of us as superficial and
even banal. It might be thought that colour merely constitutes an alternative to
black and white. Colour may merely be associated with fripperies such as cosmetics
and fashion or with football shirts, the colour of the car or decorating the hall.
Does colour really matter? Does it really deserve study and attention?
Well, yes it does. Not only is colour the stuff of art and a vital constituent of our
everyday lives, but without it the most important discoveries and advancements
of the 20th century would not have been possible. As Leonard Shlain in Art &
Physics, New York, Morrow, 1991 explains, colour has provided the key which
has made it possible for scientists to determine the elements of distant stars; to
verify that our universe is expanding; to understand electro-magnetic fields; to
penetrate the complexities of quantum mechanics and to work out the composition
of the atom.
Dabbling in this Dictionary will immediately indicate the important role which
colour performs in our everyday lives. Colour is used not merely to decorate or
to adorn. It provides us with a means of distinction. Colour is nature’s way of
helping animals to avoid predators; to attract mates; of showing when fruit is
ripe to eat or when it is rotten. Colours serve the everyday function of giving us
instructions in an effective and simple way – such as with traffic lights. Colours
provide a simple and immediate way to convey the degree or seriousness of
situations such as flood warnings, traffic congestion, danger and security alerts,
to highlight differences and to make it easier to assimilate information whether
in written form or on a computer or monitor. Colour is used as a means of
diagnosing illness or indicating the seriousness of a particular medical condition.
Doctors have, for example, recently discovered that the colour of the spit of patients
can show the severity of their lung disease.
