Psychology and perception of colour and shape

The psychology and perception of colour and shape are influenced by external factors, related to the senses of touch, taste, hearing, smell and sight. Thus, there is a need to recognise that which we perceive from our senses. Decision-making can be based on perceptions or on deceptions. Examples are drawn from the use of coloured, plastic materials in packaging displays, placed within recognition of the importance of shape and of colour in life.
