The aim of this work was to investigate the extent to which children of early and preschool age express their emotions through art works. The research was conducted in the kindergarten "Bili cvitak" in Sinj. A sample of 146 artworks by children aged four to seven was taken, and they were collected in the period from the beginning of September 2022 to the end of June 2023. The data for the research was collected with the help of documentation and observation of children's art works, and according to the principle of exemplarity, the works created through different activities of artistic expression and creation with colors were selected. All collected works of art are divided into three groups and coded according to the degree of emotional coloring. The obtained results showed the presence of elements of emotions in all children's art works, among which the degree of strong emotional coloring is most prevalent, which is most visible at an older age. However, in a slightly smaller percentage, emotional coloring and mild coloring were observed in the art works of children of early and preschool age. Such a result shows that developed emotions and their expression through colors develop in continuity with the artistic development of the child.
