People usually talk about two groups of colours: warm colours and cool colours. Scientists think that there are also two groups of people: people who prefer warm colours and people who prefer cool colours. The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active . People think that red example is exciting sociable people, those who like to be with others like red. The cool colours are green, blue and purple. These colours, unlike warm colours, are relaxing. Where there are cool colours, 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 slow in a room with warm colours than in a room with cool colours. He suggested that a warm colour such as red or orange is a good colour for a living room or a restaurant. People who are relaxing or eating don't want time to pass quickly. Cool colours 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 colours are warm and other colours are cool. However, almost everyone agrees that warm colours remind people of warm days and cool colours 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.
