📖 Read the story
Your eyes are amazing! Inside your eyes, you have tiny parts called cone cells. These cells help you see all the colors. There are three types of cells. They see red, green, and blue. When you look at a bright color for a long time, these cells get tired. This is called fatigue. Imagine you look at a red circle for one minute. Then, you look at a white wall. You will see a green or blue shape! This is an afterimage. Why does this happen? Your red cells are resting, so your eyes see other colors instead. White light is special. It has all the colors of the rainbow inside it. When your eyes are tired, they play a trick on your brain. You see colors that are not really there! It is a fun way to learn about the human body. Can you try this trick with your friends?
