Color has a considerable correlation with children's psychology and emotions, and it is a sensitive indicator. Color preference has a lot to do with personality. A child's choice of color can even reveal whether he was happy or sad at that time. It can be said that the influence of color on children's psychological characteristics is everywhere. Color is of great significance to children's mental health and personality development. Eyes are the window for children to know the world, and color is an important element of the world. The purer, brighter and more saturated the color, the stronger the visual stimulation. For example, red, orange, yellow, green, blue and purple are visually sensitive colors, which are easy to attract children's attention. The experiment of Australian psychologist Werner proves that children, especially preschool children, recognize, distinguish and choose things according to colors with strong visual appeal. It can be seen how important the role of color is in children's visual space and the tendency to attract children's psychological attention. In addition, psychologists have long discovered the regulating effect of color on people's psychological activities. Generally speaking, red makes people excited, blue makes people quiet and green makes people energetic. Dr Arthur, a famous American child psychologist, once made a one-year survey on children's colors. His research found that color has a fixed meaning for children. Generally speaking, children who love Huang are more dependent and prefer to play the role of children all their lives; Children who love blue are often bosses or selfish; Red represents strong personality, naughty and emotional; In addition to symbolizing love, pink also means a high degree of aesthetics, elegance, gentleness and consideration; Purple is synonymous with hearty, easy-going, heartless, tolerant, curious and self-motivated; Children who like orange are lively and outgoing, and have a good popularity, but they are a little self-centered, inconsiderate and careless. It is worth noting that if your child likes purple, black, dark blue and other colors, it is necessary to explore his psychological background.
