Indoor color design in kindergartens has a significant impact on the healthy growth of young children. Based on this, the article analyzes the characteristics of current kindergarten interior color design and proposes a core idea of building a layered and progressive, functional zoning, and emotional harmony system from the perspectives of cognitive laws, spatial attributes, and emotional experiences. Furthermore, strategies such as constructing a layered and progressive color matching system, strengthening color application norms guided by spatial functions, and establishing a dynamic color update mechanism are proposed to provide teachers with replicable color management solutions and enhance the effectiveness of environmental support for children's focus, relaxation, and communication.
