The great poet Nizami used in his works the power of the influence of colors on the spiritual world to embody in the eyes of the reader the countless, seemingly, means of beauty that are the charm of the universe. The colors that adorn all of humanity are unique in their amazing beauty. In the work "Treasure of Secrets" it is established that the names of white, black, gray, blue, green, red and yellow colors have a richer semantic capacity. Note that the semantic structure of colors refers to the lexical and semantic variants of a word, organized in the form of a hierarchy.

From the semantic field of black color, we can see that the actual denotations of the color soot, coal, gloomy, dark, sad, angry, youth, beauty, fun, darkness, gloom, night, mourning, mourning. In the work, the gray color is expressed through shades of gray, musky, as well as the colors of freckles, ash, amber and lead. In the "Treasury of Secrets", the red color is expressed by the tokens burgundy, manual, mute, gold, scarlet, pink, ruby, and fire. In this paper, the names of colors are developed as part of phraseological combinations, both in their real and figurative meaning. But note that not all color names are equally well developed in phraseological combinations.
