The aim of this paper was to determine the ability of children of early and preschool age to perceive and use contrast in their visual expressions. The research was conducted on a sample of 40 children aged three, four, five, six and seven, and was conducted in the "Zvončica" and "Maginja" kindergartens. The works of art were collected from March to May 2024. After the works were collected and analyzed, they were divided into three groups with regard to certain criteria and characteristics. The works are divided into a group of children's art works with an insufficiently developed sense of contrast, with a partially developed sense of contrast and with a developed sense of contrast. After the research, the results showed that children mastered the warm-cold contrast the easiest, the color-to-color contrast was moderately difficult to master, and the quality contrast was the hardest to master. During the observation of children's art works, minimal deviations were observed, which negate the hypothesis that older children better perceive and use contrasts in their artistic expression. Although this is mostly true, it is not the rule.
