This book teaches children different things that are Red. The color Red is a pretty color.Children have color likes and dislikes according to individual character and stage of development.It was believed that surrounding children with soft pastels and rounded architectural forms at the kindergarten level (2-7 years), progressing to central shared learning areas with stronger more vibrant colors for older children (7-10 years) then onto larger shared work areas in which soft greens and blues were used for children from 10 into their teenage years, was less distracting to the mental concentration of each stage of development.
