The article suggests a cognitive discourse analysis of the colour blue based on the material of the verbal and iconic levels of British and American rock-discourse. Special attention is devoted to metaphorical models of the colour blue that are rare. In other words, such metaphorical models are identified strictly in terms of only one level of specifically one studied discourse. The author also provides an overview of what has been previously achieved in the sphere of colour analysis. In general, the author discusses the specifics of 4 rare metaphorical models of British rock-discourse (verbal: BLUE - DETACHMENT / DEJECTION, BLUE - FEAR; iconic: BLUE - EXCEPTIONALITY, BLUE - PRIVELEGE) and 3 of the American one (verbal: BLUE - NATIONAL IDENTITY; iconic: BLUE - INTELLECT, BLUE - ROWDINESS). The presented results might be of interest to the researchers in the fields of cognitive linguistics, discourse theory, lexicology, etc.
