Using other attributes to describe items, such as size, texture or shape, can help a child function better than asking her to get “the yellow shirt.” Colorblind children can lead a normal, healthy life. Teaching her the position of traffic lights, for example, can help a child who cannot see red or green. Expert InsightĬolor blindness does not have to limit a child’s ability to function. If a child cannot see a certain picture or shape (usually composed of red or green dots), then there is a good chance he is colorblind. In most cases, the child is shown pictures that are composed of colored dots. If the child cannot correctly identify the colors, more testing will be given.
