The article deals with preliminary results of experimental research on the colorgraphemic synesthesia of vowels in Komi-Permyak language. The obtained data on Komi-Permyak language is interpreted in the context of data in Russian, English and other Romano-Germanic languages, obtained through analogue research. It is found that the color-graphemic synesthesia of graphons A [a] and O [o] presents a universal phenomenon with a high degree of probability. The relative dependence of color associativity of vowels on the initial consonant and the following vowel in color denomination was determined. It was concluded that Komi-Permyak graphons do not have a stable and regular link with colors, the names of which are borrowed. It is possible to assume that letters of the native language are connected with the original color denominations. A tendency of Komi-Permyak vowels, being attracted between chromatic colors (red, blue, yellow), is revealed.
