Abstract Color terms show a remarkable variation in their possible lexicalization patterns across different languages. In the literature, the interest has been especially to describe the color lexicon of a certain language and to determine whether it may abide or not by Berlin and Kay’s universal evolutionary sequence, e.g., whether a certain color denomination may be considered as a basic color term, or whether a certain color category is lexicalized by more than one basic color term, by which criteria, etc. It has not been established, however, which are the most common lexical sources of basic color terms on a comparative basis, and which semantic changes are more common in this semantic field. On the basis of data drawn from 70 ancient and modern Indo-European languages, we aim at answering precisely these research questions concerning the origin and the development of basic color terms. We discuss the various lexical sources of the basic color terms for white, black, red, green, yellow, blue, brown, gray, orange, pink, and purple, and we show the most important semantic changes leading to these color meanings. We also discuss to which extent these terms are likely to be inherited or borrowed. All this aims at being a contribution to the study of diachronic semantics.
