This research identifies and analyses the meaning of 25 collocations with color words. Collocations with color words show different meanings, depending on whether its usage is literal or metaphorical. Each culture interprets colors differently, what influences the metaphorical meanings, then, to comprehend them it becomes necessary to considering the communicative context. Evaluating the cotext and the context clues that make their meaning metaphorical or not, analyzed collocations formed by noun plus color adjective have been analyzed. The chosen colors are black, white, yellow, red, blue, green, and purple. The analysis is based on the theoretical concepts of Interculturalism, Functionalism, and Lexicogrammar so as to demonstrate that the semantic aspects of color metaphors can reveal cultural characteristics of Brazil. In order to carry out the study, fifty occurrences of each collocation, retrieved from the Brazilian Portuguese Corpus, are collected, analyzed and interpreted. A descriptive formula for each collocation is then proposed, including structure, found occurrences, considered occurrences, non-metaphorical occurrences, and conceptual metaphor. The results have shown that, in most cases, the literal meaning of the noun is maintained, and the color word suffers delexicalization, losing its literal meaning. Also, the cotext and the context are essential for the semantic interpretation of the metaphor collocation.
