It is generally thought that certain colours are associated with certain emotions, the obvious example being red for anger. If this is the case then the animations could incorporate the theories of colour and emotion, and therefore make it easier for the emotions to be conveyed.
The Psychology of Colour – S. Wu http://psychology.about.com/library/weekly/aa031501a.htm
Colours can affect our emotions and behavior. Our reactions to colors are led by a combination of biological, physiological, psychological, social and cultural factors (Wu). The concept of warm and cool colours is well known amongst researchers in this area. Warm colors generally include magenta, red, orange, yellow, and yellow-green. These colors are associated with excitement, happiness and comfort. Cool Colors generally include violet, blue, light blue, cyan and sea green. Emotions associated with these colors range from calm and peace to sadness, withdrawal and repression.
Figure 6 shows some modern colour associations. This table shows that colours can mean several things to people. It is safe to say that one person will react differently to a colour than the next person. With this in mind, further investigation of colours and emotions was needed, to try and generalise a specific colour for each emotion. It was decided that auras would be looked at to try and achieve this (see next section).
