Final answer:
Children develop full color perception by around six months of age, with their vision approaching that of adults. By age five, they can reliably identify and name colors, demonstrating a full range of color perception.
Step-by-step explanation:
When do children have a full range of color perception?
Infants are born with a limited ability to perceive color, with about three-quarters able to distinguish red shortly after birth, but fewer are able to distinguish green, yellow, or blue. However, their color perception developments rapidly and by around six months, children's vision has improved significantly, nearing the acuity of adult vision, which includes the ability to perceive a full range of colors. By the age of five, children have well-developed color perception and can identify and name multiple colors, indicating that they now have a full range of colors similar to adults.
During the early stages of an infant's life, the growth of various cognitive and psychosocial skills occurs in tandem with the improvement in vision. Five-year-old children have a rich vocabulary, the ability to sort by color and shape, and a grasp of basic numeric concepts such as counting past 20. These developmental milestones all include the interaction and understanding of various colors, showcasing children's full color perception.
