This presentation will describe artists, practitioners and scientists, who were interested in developing a deeper
psychological, emotional and practical understanding of the human visual system who were working with wavelength,
paint and other materials. From a selection of prints at The Prints and Drawings Department at Tate London, the
presentation will refer to artists who were motivated by issues relating to how colour pigment was mixed and printed, to
interrogate and explain colour perception and colour science, and in art, how artists have used colour to challenge the
viewer and how a viewer might describe their experience of colour.
The title Colour in Flux refers, not only to the perceptual effect of the juxtaposition of one colour pigment with another,
but also to the changes and challenges for the print industry. In the light of screenprinted examples from the 60s and 70s,
the presentation will discuss 21st century ideas on colour and how these notions have informed the Centre for Fine Print
Research's (CFPR) practical research in colour printing. The latter part of this presentation will discuss the implications
for the need to change methods in mixing inks that moves away from existing colour spaces, from non intuitive colour
mixing to bespoke ink sets, colour mixing approaches and colour mixing methods that are not reliant on RGB or CMYK.
