Lighting and architecture workshop
Paint workshop
Management committee meet at Bristol
Colour mixing workshop
Digital print workshop

A selection of 20 CREATE veterans attended a week-long CREATE Masterclass on Colour, appearance, and lighting. The course was held at the CFPR studios, UWE Bower Ashton campus, Bristol, in October 2010. The delegates included researchers from industry, further eductation institutes and independant artists working with colour throughout Europe.

The week-long masterclass consisted of a selection of extended, in-depth experiments and workshops; the abstracts of which are below.

Workshop 1: Capturing real world with fake images 
Alessandro Rizzi University of Milano

This workshop will present the problem of fidelity in digital images from cameras. A large set of image processing and colour management itself start from the assumption that digital imaging (not considered the gamut limitations) is a truthful representation of the acquired scene.
In this workshop, participants will test the acquisition of a real calibrated scene with their own cameras. Please bring your own camera and if you have more than one, bring all of them. You’ll be surprised.
Why light distribution correctness is not so important? Results will be collected and discussed.


Workshop 2: How accurately can we reproduce a colour from memory?
Carinna Parraman, CFPR University of the West of England, Bristol

The question is motivated by whether we can ‘see’ and ‘hold’ a colour and then reproduce this accurately? And whether our memory for colour is innate or can be enhanced and improved. The objective is to investigate how humans can accurately record – through colour mixing - the appearance of coloured objects in a scene, and secondly how well they can recall and accurately reproduce these colours at a later point in time from memory.

The first part of the session will involve you recapping on how to mix paint: from primary colours to create secondary colours and then creating tints and tones.  The objective is for you to familiarise yourself with the different primary colours and their limits in the colour gamut.

You will also be asked to devise your own ideal colour palette: the colours that you tend to unconsciously choose or gravitate towards. This will involve a certain amount of colour experimentation.

The last part of this session will be the start of the project, which will continue through the week. You will be asked to observe three sides of a lit colour cube for a period of time and then recall these colours from memory. The box is then covered and you will be required to paint the three colours you have memorised. This experiment will be repeated throughout the week, and new colour challenges presented each session.


Workshop 3: Illumination and appearance
Markus Reisinger, University of Technology Delft, Philips Research Europe

Light is a fundamental property of our daily lives, as not only does it make things around us visible but it influences the appearance of those things too. This workshop explores how human perception of material characteristics and appearance alters under different illumination conditions.
The two objectives for this workshop are to analyze the impact of lighting on the visual appearance of different materials and to create situations that elicit perceptions of soft and hard object appearance.
This is also in the attached file that describes the whole workshop setup and required materials and lighting.

Workshop 4: Colour Naming
Dimitris Mylonas, University of Liverpool & TruColour Ltd.

This workshop aims to bring attendees up-to-date with the latest information on colour naming and colour categorization within and between different cultures. Participants will have the opportunity to play a physical colour communication game and win fine art prints illustrated by Valero Doval. Drawing on that experience your cognitive aspects of colour will be compared with thousands of participants of a colour naming experiment conducted over the Internet. Multiple factors that influence colour categorization will be discussed with practical examples. This international workshop should be of interest to those associated with colour technology, colour in art and design, colour psychology, computer vision, linguistics and communication studies.

At the conclusion of this workshop, you will know that successful colour communication requires user-centred design thinking and you will have an insight about the order that colours are recognised and identified. The instructor is the principal researcher of an online colour naming study (Available: http://colornaming.net) currently translated in seven languages with over 1700 participants.


Project 5: Digital printing, colour management, profiling, printing – based on the work undertaken from project 2 (Paul Laidler and Carinna Parraman)

Project 6: Impact of Light and Colour on perceived Space
Birgit Schulz, TU Graz, Faculty of Architecture, Institute for Spatial Design

Lighting can change the perception of space. We will explore this by using a paper model and put it in a real space. This workshop is about the experience and perception of light and colour. The appearance of colour will be observed with the help of a lit paper model. Produced reflections and shadows change our impression of the observed space. In a series of trials we will study the interaction between light, colour and space and examine it in detail.

Workshop programme:

  1. Introduction
  2. Cut out the paper model and glue it together
  3. Small exercises to experience the interaction of light and colour
  4. Document the experienced lighting in your personal way (sketches, description in words, photos,..) accurately enough to explain your experiences to someone who doesn’t have the chance to follow the exercises.
  5. Presentations and discussion of personal experiences and learning’s

                        Total: 4 hours
