When do infants' color vision begin to develop and become established?

• A. Begins to develop by 4 months and is established by 7 months.
• B. Begins at birth and is established by 3 months.
• C. Becomes fully developed by 12 months.
• D. Never develops until after 12 months.

Answer: (A)

Color vision in infants develops as the retina’s cones mature and the brain’s visual pathways become more integrated. At birth, color discrimination is limited and newborns mainly see contrasts in brightness. By about four months, they start to detect and distinguish colors, and by around seven months the system is established and functioning in a way that is very similar to adults. This progression supports infants’ ability to reliably notice and pursue colored objects, which aids exploration and learning. That’s why the timeline of beginning to develop by four months and being established by seven months best matches what we see in typical development.
