Observe what colors your child is familiar with when they watch the characters as they meet them on a cartoon. Please note that the kid paints his favorite characters accurately and thoroughly.
Try to use a themed coloring. For example, a series of coloring books about animals, buildings or machines give children an idea of the objects of the world. Coloring of fairy tales or cartoon characters, are good because they allow the child to "talk" with their favorite characters and express their attitude towards them through colors.
