Colour Vision Assessment and the Use of Colour in Clinical Practice
Wednesday 11 October 2017
14.00 hrs City University London, EC1V 0HB

This seminar will also focus on use of colour for prevention and treatment of conditions encountered by the eye care practitioner. Specifically, we will discuss the use of coloured overlays and lenses for reading difficulty, and the use of short wavelength filters. Both of these interventions are widely applied in practice yet both are controversial.

Northern Chapter
Tour of Unison Pastels Factory
{CG(GB) members only}

Wednesday 19 July 2017
Thorneyburn, Hexham, NE48 1NA

The Northern Chapter had a private tour of Unison Colour for its Summer visit.  Unison Colour began in the early 1980s when artist John Hersey found that mass-produced, factory-made pastels simply did not offer the qualities he was looking for, so he decided to make his own.  Today the company hand-make over a quarter of a million sticks a year! Set amongst rolling hills of the beautiful Northumberland countryside, this family run business is now run by Kate Hersey and her son Dan.  For our exclusive visit we were treated to a tour of the pigment room and a demonstration of the art of hand rolling and preparing the coloured pastels.  Each colour has a recipe attached to it created by John Hersey to which the friendly staff, all local, adhere to this day.  The highlight of the visit was an opportunity to play with the pastels and explore our creative sides.
 Our visit culminated with tea and shortbread in the country kitchen around a large wooden table where the members had a chance to ask more questions, buy the products and take a tour of the house.   For further information on Unison:

Colour by numbers: the art of reproduction in the 21st century plus
Encounters with Colour: a Neurologist's Viewpoint
Wednesday 03 May 2017
City University, London
Carinna slide
After the AGM, the retiring Chairman, Carinna Parraman, delivered her address on reproduction in the 21st century: from printing on fabric to printing dresses in 2.5D, from wall paper to exact replicas of old masters complete with 3D brush strokes: the master printers of even 40 years ago would be amazed at what was now possible.
Gordon Plant (The National Hospital for Neurology and Neurosurgery, Queen Square, and Moorfields Hospital) then delivered a fascinating Cook's Tour of the neurology of the visual system. He reviewed what patients with problems might experience. Fuzzy images, blind spots, lumious phenomena that were not real but internally generated, and changes of percieved colours. Fortunately some patients were able to draw what they saw - one example he described was the migraine aura "seen" by Sir Hubert Airy ( yes, the Airy of the Airy Disc) which he drew with colour and zigzags - a classical picture of symptoms which several members of the audience were unfortunatley able to confirm.

Northern Chapter
Wednesday 26 April 2017
Cobalt Studios, 10-16 Boyd Street
Newcastle upon Tyne, NE2 1AP
Cobolt 2
The Northern Chapter was welcomed by a trio of artists based at Cobalt Studios in Newcastle's creative quarter, Ouseburn. Mike Collier, Alex Charrington and Susi Bellamy gave members a guided tour of their respective studios, showing them the world of professional artists for whom colour represented emotion, meaning and even a scientific challenge. Alex spoke of the challenges facing colour reproduction that printing technologies compounded, and talked through the process of a collaborative project focussing on colour, depth and form to explain how he overcame these barriers. Mike spoke of colour as a language, much like the written word, and how his colour choices linked to memories of nature walks his work is based on. Susi let members into her 'private playing space' for colour - where experimentation and reconstruction form an essential part of her art practice.
Afterwards tea was served at Ernest, the cafe next door .

Inspiring Books on Colour
Wednesday 05 April 2017
Seminar Room, Royal College of Art, London SW7 2E Speakers team There was a sell-out and a waiting list for this event at the RCA where five speakers (ABOVE) described and reviewed their chosen books (see details). From left to right the speakers are Roy Osboure, Joyce Dixon, Alexandra Loske, Stuart Durant and John Mollon The feedback was very positive and the CG(GB) will have to follow up this sytle of event. There does remain one question though; why do the men look so serious and the women happy?

Monday to Wednesday 27 - 29 March 2017
BFI Southbank and Friends House, London

Opening shot This image above came from the start of the conference: Day 1 NFT3 at BFI Southbank.

The Conference opened on 27th March 2017, at the National Film Theatre 3, BFI Southbank and continued in the Friends House, Euston for two more days. The event was co-organised by the Colour Group (GB) and the Institute of Applied Sciences (HTW), Berlin and in co-operation with the University of Zurich, British Film Institute (one of our Patron Members) and the University of Bristol - The Eastmancolor Revolution and British Cinema, 1955-85. There were further supporting organisations: San Francisco Silent Film Festival, USA; ARRI, Munich; Czech National Film Archive, Prague; Deutsches Filminstitut – DIF, Frankfurt am Main and Aardman Animations, Bristol.

Trumpy, A Stockman, E. Watkins. (Notice the skillful use of black and white photography at a conference on colour - very cool)

The Conference is establishing itsplace amongst the regular scholarly events on colour in historic film. Discussions ranged from restoration, preservation and digitalisation through to the science of restoration and how the human visual system enables the illusion of moving images, as well as discussions on the aesthetic and semantic values of colour in films from different eras.Speakers were from the UK, Germany, Switzerland, the Czech Republic, the USA and Australia.
The was a sell-out with 100 participantswhich was the maximum number that could be fitted into the venu. In 2016 participants were from six countries, but in 2017 they were from 12: the UK, Germany, Austria, Switzerland, the Netherlands, Spain, Portugal, Poland, Czech Republic, Norway, the USA and Australia.

NEWS RGB bacteria


In a study published in Nature Chemical Biology, MIT researchers manipulated E coli genes so that they respond when illuminated by red, green, or blue light they fluoresce red, green or blue. So a coloured image projected onto a bacterial mat causes the bacteria to emit red, green or blue light thus becoming a living display. This won't replace LED or plasma screens but is a useful step on the road to fully understanding gene manipulation. If you can stomach the breathless journalism you can read more at on the ARS Technic UK web pges or better, read the original.

The history of printing is not in black and white. Colour played an essential role in print culture even before Gutenberg printed his Bible, but it has long been hidden in plain sight because colour printing is rarely recorded. old colour print
This interdisciplinary, introductory course provides an overview of colour printing techniques in the West from manual techniques c.1400 through the development of chromolithography in the mid-1800s.
The Institute of English Studies, University of London, is offering this week-long course running 10 to 14 July as part of the London Rare Books School (LRBS), with reduced fees for students. Further details at here. Other courses at this year's LRBS can be found here: here.

CG(GB) Sponsors Prizes

The CG(GB) has agreed to sponsor two student prizes for the meeting at IC. The meeting is described so:
Ever since humans contemplated replicating the flight of birds, biomimetics has sought solutions to complicated problems by examining how Nature, with the advantage of several millions of years of evolution, has tackled them before. Nowhere is this more apparent than in optics where some of the rich optical behaviour presented through evolutionary nano-structuring can now be replicated to our advantage in the laboratory. Structural colouration of morpho butterfly wings, for example, was recently commercialized to produce interferometric modulation to define pixel colouration in displays.

Red Project Notice


Following a very successful RED EVENT last December, the Norhtern Chapter of the CG(GB) has had the idea taken up by the Northumbria University School of Design which has put in a colour red show in their atrium - everywhere you look it's RED.

Book Cover


M ichel Albert-Vanel's book Planetary Colour System (PCS) is now published in English and the image above is of the cover.
The author has lectured for more than 30 years at l"Ecole Nationale Supérieure des Arts Décoratifs in Paris and gave a presentation at the CG(GB) on Colours in India in April 2014. The PCS is a colour-order system which has been shown to be effective in various applications such as the classification of paintings and images. It helps the user's understanding of the art and can become a powerful creative tool.
The book is only available from the author by email: The cost is 49€ + 20€ (postage to UK).

W hy are the 'colours of Christmas' red and green'? Who said Santa should be red? Coca-Cola? Dr Spike Bucklow last year presented his ideas in Cambridge. It is, it seems, those pesky old medievals who are to blame. Check it out and enjoy your pud with a piece of green holly with red berries come the 25th.

W ell, the letters stand for British Association of Film, Television and Screen Studies and they want to form a Special Interest Group on Colour and Film. Colour and Film thus encompasses, but is not limited to, questions of film making, exhibition, archives, film history and analyses from early film to narrative cinemas and experimental film, genre, theories of subjectivity, colour and affect, sexuality and philosophy. The Group welcomes members interested in all aspects of Colour and Film, its history, theories, preservation and aesthetics, so far including scholars, filmmakers, archivists and film conservation specialists.
