The aim of this paper is to investigate the extent to which color sensitivity is present in children of early and preschool age and at what age it is most pronounced. The research was conducted in the kindergarten Čarobni pianino and in the kindergarten Radost in Split. A sample of 208 children artworks aged three, four, five and six years was taken, and they were gathered in the time period that lasted from the beginning of February to the end of May 2021. The data for the research were collected with the help of documentation work, i.e. by observing children artworks. From each educational group, children artworks were selected, which were created through various activities of artistic expression ang usage of colors in art creation. All gathered artworks are divided into three groups depending on the characteristics of artistic expression for a particular age. The obtained results showed the highest prevalence of artworks that indicate a moderately developed sensibility, which is marked as the average artistic expression of children in early and preschool age. However, what also has been noticed was a large number of artworks which indicate an underdeveloped color sensitivity, which is significantly higher compared to those that indicate a developed color sensitivity. Although the developed color sensitivity is the least represented, it can be observed that its number gradually increased with the children’s age. Finally, such a result shows that a more developed color sense and its use develops in continuity with the child’s artistic development.
