T he work deals with the following issue: Colours per se and combinations of colours eligible for registration as trademarks. Recently, the rapid development of technology offered the consumers the opportunity to perceive and the forms of less traditional trademarks, acting in a specific manner upon fillings, namely by means of colours, aromas, sounds. Colours and combination of colours play an important role in distinguishing goods on the market, being extremely useful in cases when the traditional trademarks are not easily perceptible. The main purpose of the work is argumentation of the need for registration of colours per se and combinations of colours as trademarks or companies are seeking for new possibilities of highlighting goods not only by words and figurative signs but also by certain colours perceived, incontestably, more easily by the consumers than other trademarks. The excessive offer of counterfeit goods undermines confidence in the known trademarks, decreasing the volume of home and foreign investments, since the capital is invested there where protection of intellectual property is much more confident. Protection of trademarks of such type needs special provisions in the law. Refusal of applications for the registration of trademarks - colours per se and combinations of colours, involves infringement of the producer’s rights and, what is not less important, of the consumer’s rights. As researches state, the large companies, acting in the region, consider that enforcement of an effective protection in the field of intellectual property needs close cooperation between the private sector and the state authorities.
