Companies often try to use a particular colour or colour combination on their goods or packaging materials to give their products a consistent look and to distinguish their brand from their competitors' product offerings. The use of a certain colour or colour combination can, over time, create an overall distinctive look that is recognizable and identifiable solely with the source of the products, so that a product (or packaging) with a certain colour (or combination of colours) signifies a particular brand in the mind of the consumer.
