People have been interested in color and its effects for hundreds of years. More recently, research has turned to the question of how different colors can help students learn better.
Believe it or not, some colors can affect a child's IQ（智商）. For example, a simple black and white color scheme may cause IQ to become low, while the good use of reds and oranges may raise it as much as 15 points. Be careful not to use too much, however; a little red is exciting, but too much makes people uncomfortable. Bright yellow is exciting to the brain, while the color green is thought to encourage creativity.
Use blue and green to calm yourself. Blue, especially, can cause you to calm down. Something blue in a reading area, for example, may help you focus（集中于） on what you are reading. But too much dark blue can make you sad, so use light blue on walls or large floor areas.
If you are struggling to read, try a different color of paper. According to a study, 80 percent of children who had difficulty in reading improved their understanding when they put something grey or blue over their pages. Do not use bright colors here, as they become difficult to look at after a while.
However, use bright colors like red, orange and yellow for important points. These colors attract the eye and may help you notice details.
The same color of the walls of a room do not help you focus on your studies, but make you slow in understanding. Colors, on the other hand, make the senses active and encourage learning. Use primary colors red, yellow and blue in a proper way. Then how do you make your choices of color? It mainly depends on（取决于）your space, the lighting and the function (功能) of the room.
