Collaborative research and advertising expert ophthalmologists doctors showed that the human eye can not simply allocate some colors and their combinations, but "remembers" and issues in the case of associative images, or close such a stimulus. Sounds complicated, but as a very, very much in this world, in fact extremely simple. The man, who saw the combination of black and yellow (quite a contrast, you see) instantly recalls or implementation, or a company "Bosch", or a cellular operator "Beeline". Similarly, red label "Nescafe" for the human brain is the next message: coffee, vivacity, quickness. And the situation persists for many color combinations.

Obviously, the packaging of milk paint in red, yellow and black colors of the more – rather stupid to do. This is sure to alienate customers. But the combination of white (clouds), green (grass) and blue border is consistent with both the product itself and human understanding of the word "milk." That took this way, for example, designers to create packaging of dairy products "Buttermilk". It is equally well resolved packaging for bakery products – a moderately yellow, sand and slightly brown in color. Now it is clear: the scientists were right – the eye transmits information about the combination of colors in the brain, where in response to an association of positive or negative. But this fact does not deny the possibility of creative solutions in product packaging design – sharp beating in the eye color is easier to remember and can attract children. For example, the main weight boys choose cars black and red or red with yellow flowers. At the same time, girls are more attracted to less bright pink, blue and green pastel tones. All these features of the human psyche (in this case in different age groups) should be considered when developing design colors appearance and packaging of goods.
