The article presents the results of an experimental study on the interpretations of the colour red in British and American linguocultures, which was carried out on the material of the rock discourse of these linguocultures and consisted of three stages: preparatory; experimental; final. The goal was to establish whether the psychophysical, linguocultural and lexicographic data about this color in the British and American linguocultures, identified at the preparatory stage, correspond to the actual perception and interpretation of the red color by speakers of English as a second language. According to the results of the first block of the experimental stage (open question), the respondents' answers were divided into two groups - associative definitions and metaphorical associations. Most of them correspond to the data of the preparatory stage. In the second part of this stage, all of the three interpretations of red (“energy”, “revolution / radicalism”, “danger”), identified at the preparatory stage, were successfully established by the respondents when analyzing the proposed covers of British and American rock discourse. For each of the six studied rock covers, it was possible to establish additional interpretations of red. In the third part of the experimental stage (closed question), all interpretations of the color red, determined at the preparatory stage with the help of psychophysical, linguocultural and lexicographic data, were somehow chosen by the respondents, which confirmed their relevance in relation to the studied linguocultures.
