Do 5-m.o. babies see all colors?

At three to five months old, the baby starts to differentiate different colours, especially between similar bold colours and will progress to noticing subtle differences in pastels. One can try to encourage a baby's interest in primary colors and pastels as his/her colour vision develops. Hang mobiles that are primary-colored at the crib, have colorful posters around the house/room, and give the baby visually striking board books.

It is not until around the 5th month that the eyes are capable of working together to form a three-dimensional view of the world and begin to see in depth. Although an infant's colour vision is not as sensitive as an adult's, it is generally believed that babies have good colour vision by 5 months of age.
