In the literature the conclusions concerning the influences of colours on human performance and well-being are often conflicting. This can be caused by the artificial setting of the test process. Applying questionnaires could also be a cause. To avoid the disadvantages of an artificial setting, a colour research process was organized in a real life setting. In order to get a better understanding of the validity and possible pitfalls in using questionnaires, the responses to the questionnaires were analysed. During colour research looking for the colour influences on perceived productivity, social cohesion and well-being during meetings, responses to questionnaires were compared with findings from observations of behaviour and additional interviews with the respondents. Discrepancies were found indicating weaknesses of applying questionnaires in colour research. The findings suggest that questionnaires alone are not a fully appropriate tool to establish the colour influences. Triangulation by observations, additional interviews and sampling techniques can improve the validity of measuring the influence of different colours.","questionnaires; observations; methodology; social psychology; colour influences","en","journal article","","","","","","Accepted Author Manuscript","","","","","Applied Ergonomics and Design","","",""

The impact of colour on perceived productivity, social cohesion and wellbeing","Bakker, I.C. (TU Delft Applied Ergonomics and Design); van der Voordt, Theo (TU Delft Real Estate Management); de Boon, J; Vink, P. (TU Delft Applied Ergonomics and Design)","","2013","The purpose of this research is to establish the influences of the colours red and blue on perceived well being, social cohesion and productivity in complex real life work conditions during regular meetings.
Methodology: Seven regular government teams held seven regular meetings in a red, blue and reference meeting room. In literature it is often mentioned that red is a warm and blue a cool colour. To be able to test the warmth and coldness effects we have amplified the warm and cold qualities with light colour and colour of the table top desk. We asked employees to complete questionnaires concerning perceived well being, social cohesion and productivity. Fifty two subjects completed three questionnaires, at the start, the end and two or three days after the meeting. Data were analysed with SPSS 16.
Our findings didn’t show any effects of the red and blue environment on perceived well being, social cohesion and productivity. We assume the processes in real life work situations are too complex to measure influences. Practical implications are that statements frequently mentioned in literature concerning influences of red and blue might be not valid in real life meeting settings. New ways of testing the impact of colours should be reconsidered. Because lab situations are too simplified and artificial, we suggest testing influences of colour in an isolated setting in relation to art.
The originality of this research concerns testing colour influences in complex real life work settings like meetings.","meeting rooms; colour influences; red and blue; perceived productivity","en","journal article","","","","","","Accepted Author Manuscript","","","","","Applied Ergonomics and Design","","",""
