Parents can let their children start by distinguishing colors, and usually let them see things of various colors.

At the same time, parents should say "This is a red balloon" and "This is Huang Xiangjiao" to enhance language stimulation.

Parents must also let their children know more. After half a year old, children have a general understanding of what adults say. At this time, parents can teach their children to answer by nodding and shaking their heads.

At the beginning of teaching, only two colors are taught, and when children can initially identify, they are taught to identify multiple colors.

Parents can name a color and let their children look for items of the same color with their eyes.

By teaching children to identify strangers, they can also enhance their visual discrimination.
