The core area of Tianhe Children's Park includes smaller fields dedicated to basketball, football, climbing and balancing, swings, sand pool, etc. Most facilities are painted in bright primary colors, which helps with sight development. In infancy, babies start to perceive color around 2-4 months old. At first, they can distinguish between red and green, gradually expanding their color recognition to include yellow and blue. As toddlers, children begin to show color preferences. These preferences can be influenced by various factors, including gender stereotypes and cultural norms.
