<![CDATA[From the intial observations conducted by the researcher regarding the ability to recognize colors at TK Negeri Pembina 1 Kota Bengkulu, it appears that children’s ability to recognize colors is still not optimal because the teacher only teaches through activities such as drawing, painting, or naming colors around them. Therefore, educators need diverse activities to improve children’s color recognition skills. One of them is the rainbow rain experiment activity. This study aims to examine the effect of the rainbow rain experiment activity on children's ability to recognize colors at TK Negeri Pembina 1 Kota Bengkulu. The research method used is a quantitative pre-experimental design with a one-group design. The population of this study is all students at TK Negeri Pembina 1 Kota Bengkulu in the 2024/2025 academic year. The sample was taken using a simple random sampling technique. Thus, class B5 was selected, consisting of 11 students as the experimental and control class. Data collection techniques used observation and documentation. The obtained data were analyzed using validation tests, prerequisite tests, and hypothesis tests. The hypothesis test analysis results showed that the Sig. F value = 0.040 (< 0.05), which means there is a simultaneous effect, so the working hypothesis (Ha) is accepted while the null hypothesis (Ho) is rejected. The significance value of the rainbow rain experiment activity is 0.030 (p < 5%). This means the rainbow rain experiment activity has a significant effect on children's color recognition ability by 0.733. The R² value = 0.302 indicates that the rainbow rain experiment activity contributes 30.2% to children's ability to recognize colors]]>
