Child care Center is an important place for pre-school education, and since infants spend most of their lives in nursery places, nursery places play an important role in the development of infants. Among these, the color of interior space has an important influence on a child`s psychological, physiological, and lifestyle. The growth and development of infants is closely related to color, and through the experience of color, infants feel stability and excitement in space. In the color scheme of the nursery space, reasonable color placement should induce the infant to meet the psychological needs and develop the baby`s sensibility. The purpose of the research is to analyze the color psychology of infants and study color perception and sensation of babies through the indoor space. This will be provided as a material on the rational color arrangement in child-care spaces at daycare centers according to the color psychology of infants. The analysis is carried out by means of 2 spatial cases. This study are: A(IBOBI International Child care Center),B(Victoria Child care Center). Through the case, we have drawn conclusion. Color is used as the most powerful expression language in the interior space of a daycare center, dividing the space into a space environment to create an atmosphere, control the emotions of infants, and induce the emotions of infants. The color arrangement of childcare spaces is arranged according to the color preference and psychological impact of infants by age.
