In general, people talk about two groups of colors: warm colors and cool colors. Scientists think that there are two groups of people: people who prefer warm colors and people who prefer cool colors.
The warm colors are red, orange and yellow. Where there are warm colors and lots of light, people usually want to be active. People think that red example is exciting sociable (善交际的) people, those who like to be with others like red. The cool colors are green, blue and purple. These colors unlike warm colors, are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting but one scientist says that time seems to pass more slowly in a room with warm colors than in a room with cool colors. He suggested that a warm color such as red or orange, is a good color for a living room or a restaurant. People who are relaxing or eating don’t want time to pass quickly.
Cool colors are better for offices of factories as the people who work there want time to pass quickly. Scientists don’t know why people think some colors are warm and other colors are cool.
However, almost everyone agrees that warm colors remind people of warm days and cool colors remind them of cool days. Because in the north the sun is low during winter, the sunlight appears quite blue. Because the sun is higher during summer, the hot summer sunlight appears yellow.
