People who score high on activity are generally bussy and energetic. They love all kinds of physical activities, hard labour and physical exercises included. They get up early and quickly, jumping from one activity to another and have a wide range of interests. People with low scores are physically inactive, lethargic and easily tired. They always move at a calm pace and prefer quiet and calm holidays. High activity is a characteristic of the extrovert and low of the introvert.
Eysenck, H. J. (1998)

The chroma level has an effect on activity (Miyamoto, 2003). The brighter the colour, the more a sense of dynamism will emerge (Valdez & Mehrabian, 1994). The psychologists da Pos and Green-Armytage (2007) obtained the same result in their research into colours and basic emotions. Passive feelings such as sadness and fear are associated with very unsaturated monochrome colours, while active feelings such as happiness, surprise and anger are linked to bright and very contrasting colours.
