Children who choose a combination of black and red are actually explosive children. They may have accumulated stress but are suppressing it. However, if this happens repeatedly, it becomes the child's personality and individuality. The child may suppress their anger or energy and then explode all at once, which can sometimes make us flustered. They can aim for a huge hit. Just like a home run hitter holds the bat long and aims for a home run. They also have a mindset of striking out or going home. They also have a study style that focuses on a short period of time.
