Сolor, as is well-known, is one of the important and interesting elements not only in art, literature, architecture, etc., but also in terminology. In various fields of science, technology, agriculture, etc. there are a significant number of terms, the components of which are coloronyms. The article deals with systematization and analysis of botanical terms with the element “red-”, which constitute a special layer in the term system of the Russian language. With the exception of medicine and anatomy, terms of other scientific fields containing coloronyms have not yet been the object of special research using the material of the Russian language. This article aims to fill, to a certain extent, the existing gap in this area. In general, botanical terminology is a macrosystem in which each term corresponds to its microterminal system according to the sections of botany. In accordance with this, the material we have identified is systematized and considered according to the following specific groups and models: adjective composites with the element “red” + leaf; fetus; flower; stem; petiole; trunk; root; stamen; head of cabbage." Our research revealed the following facts: 1. the basis for the nomination of some plants is not only the color of their stems, leaves, flowers, fruits, trunks, etc., but also the shape of their leaves; 2. the most productive in the formation of the category of terms under study is the word “leaf”; 3. the total number of adjectival composites with the element "red" that we identified is 84. The considered botanical terms containing the element "red" contain information about these representatives of the flora. Thus, the category of color acquires special significance when studying a specific plant species and affects its nomination (color of leaves, fruits, flowers, stem, petiole, trunk, root, etc.).
