Apart from clear and conscious stimuli, there are also short-term impulses of lower intensity which can not be consciously observed and are called subliminal messages. These are the messages on boundaries of human perception which neither the eye can register nor the mind can detect on a conscious level. And that is their purpose; to bypass the conscious part of the human mind and to direct a certain suggestion into the subconscious, excluding the resonance and the deliberate judgment. This "technique" has been explored and used for decades in the field of marketing, i.e. its branch called neuromarketing. Such advertising has been considered morally dubious from its beginnings. Ever since 1917, when the American magazine "The Saturday Evening Post" reported that the painter Norman Rockwell had sex, people began to perceive the use of subliminal messages in the advertising industry. From then on, subliminal messages have been widely used in the film and music industry, commercials, cartoons, etc. Almost everyplatform where their "power" can be used. Even though current research has shown that hidden messages are most often related to sex, which allegedly encourages the purchase of products, in this paper, such connotations will not be taken into account. This research is exploring the possibility of influence by means of subliminal messages on humans as design consumers. This research excluded the finished products that are found in human everyday use to avoid the possibility of sentimental or emotional selection, even though their subliminal message is hidden. For this reason, the paper explores the influence of sublimated messages on consumer's preference in selecting certain elements of design, shape or color. The ultimate goal is to explore whether human subconscious can be influenced by elementary design in order to draw the attention of the user to what the designer wanted to do with his work and thereby to shorten the path to the ultimate goal of product sales.
