In the process of creating a kindergarten environment, color is one of the core visual elements. It relates to children's spatial perception, psychological state, and behavioral choices, and can play a very important role and value in dividing the functions of activity areas. To enhance the quality of functional division in kindergarten activity areas, this article conducts a series of analyses and studies on the role of color in the division of kindergarten activity areas. The results show that specifically adopting strategies such as scientifically planning colors, enriching color layers, and adapting to scene requirements can not only create an environment that highly matches the activities of different areas, but also align with the age characteristics of children, thereby fully realizing the role of color in the functional division of kindergarten activity areas.
