Developments in technology have meant that computercontrolled
imaging devices are becoming more powerful and more
affordable. Despite their increasing prevalence, computer-aided
design and desktop publishing software has failed to keep pace, leading
to disappointing colour reproduction across different devices.
Although there has been a recent drive to incorporate colour management
functionality into modern computer systems, in general this
is limited in scope and fails to properly consider the way in which
colours are perceived. Furthermore, differences in viewing conditions
or representation severely impede the communication of colour
between groups of users.
The approach proposed here is to provide WYSIWYG colour
across a range of imaging devices through a combination of existing
device characterisation and colour appearance modeling techniques.
In addition, to further facilitate colour communication, various common
colour notation systems are defined by a series of mathematical
mappings. This enables both the implementation of computer-based
colour atlases (which have a number of practical advantages over
physical specifiers) and also the interrelation of colour represented in
hitherto incompatible notations.
Together with the proposed solution, details are given of a computer
system which has been implemented. The system was used by
textile designers for a real task. Prior to undertaking this work,
designers were interviewed in order to ascertain where colour played
an important role in their work and where it was found to be a problem.
A summary of the findings of these interviews together with a
survey of existing approaches to the problems of colour fidelity and
communication in colour computer systems are also given. As background
to this work, the topics of colour science and colour imaging
