Color terms are a radiation of human conceptual system that represent a reflection of his cognitive and linguistic features. Human conceptual system is fundamentally metaphorical in nature. Metaphor is a cognitive mechanism and one the linguistic strategies that can play a part in color term formation and categorical extension of colors. This study has taken metaphor in Persian color terms and metaphorical structure of color categories in Persian language into consideration. In this study, based on cognitive lexical semantic approach and theoretical thoughts of Lakoff and Johnson (1980), 910 color terms in Persian have been analysed. After description of semantic domains in metaphorical formation of Persian color terms and analysis of metaphorical structure of Persian color terms, the frequency of semantic domains application in Persian color terms and color categories’ tendency for participation in metaphorical structure of Persian color terms have been investigated. Metaphor is one of the cognitive mechanisms that has a significant role in formation of color categories and their conceptual extension in Persian language. The domains whose phenomena have been observed in the metaphorical structure of Persian color terms are: plant domain, animal domain, food domain, body domain, mineral domain, natural phenomenon domain, things domain. The frequency of application and distribution of these semantic domains in Persian color categories is not equal. Besides, the rate of color categories’ participation in the metaphorical structure of Persian color terms and their tendency to the source semantic domains vary in metaphorical mapping.
