192 A DICTIONARY OF COLOUR
c grey
The colour of lead and of ash and of the hair of the middle-aged; a mixture of
black and white. A bleak colour but perhaps resurrected by the Chinese
government’s decision to paint the buildings of Beijing grey as part of its bid to
stage the 2008 Olympic Games – ‘Grey matches our climate, cultural background
and tradition’ says Beijing as reported by The Times (7.11.00) in what must be
one of the very few Leaders devoted to a colour. An achromatic hue. An example
of how colours are used as nouns occurs in Marks & Spencer’s explanation of
why their 1999 half year pre-tax profits halved to £546.1 million – ‘we bought too
much grey’. A colour used in this way, that is in a referential sense, is intended
to include all shades of the colour whereas a person using a colour term in an
adjectival or descriptive sense has a particular hue in mind.The part of the brain
which perceives and processes grey-scale images is different from that part of
the brain which deals with colour. The US spelling is ‘gray’.
n grey area
A problem or issue which does not admit of a clear unequivocal answer or
resolution; something which has ill-defined characteristics; something with features
causing it to be positioned between two extreme categories by virtue of having
some of the characteristics of each category.
n grey economy
That element of a country’s economy generating income from activities (such as
moonlighting and housework) which, though not part of the illegal black market,
are not included in government official figures.
n grey goo
The science fiction term devised by Eric Drexler in The Engines of Creation and
extended by authors such as Michael Crichton in his novel Prey to describe the
mass of useless objects which could be created by the application of
nanotechnology thus causing a blight on the surface of the earth. Nanotechnology
could, in theory, give rise to uncontrollable minute robots (or nanobots)
replicating themselves without human involvement and manipulating molecular
structures so as to be able to create new objects. However, this is thought not
to be a merely hypothetical risk. The astrophysicist Sir Martin Rees in his book
Our Final Hour warns of the risk of nanotechnology ravaging civilisation unless
research in this area is controlled and Prince Charles in April 2003, with the support
of environmentalists, has joined the clamour for more serious debate with a view
to avoiding a doomsday catastrophe resulting from grey goo experiments.
