Colours Astonishingly, we live with a wide range of colours and yet fail to perceive their tremendous influence on daily life. The principle behind this is the fact that has been discovered by scientists for decades——colour alters our feelings unconsciously. Therefore, properly applying colour schemes in decoration utterly uplifts people’s moods and improve the quality of life. It is interesting to notice that different catalogue of offices chooses distinguished painting style. A notable example of this is that IT companies like Apple and Google are more inclined to add yellow embellishments in the software engineers’ offices because it is generally acknowledged that yellow stimulates innovation as well as imagination. However, teachers’ offices are usually painted in blue and white, rarely in bright colours, which might distract them and decline the efficiency. It is particularly true for workplaces of white-collar workers so that they could stay concentrated, logical and calm to get their tasks done without any mistake. We can also see the huge differences that colours make in hospitals. White sheets and walls send out the message that the hospital is safe and clean. Furthermore, the signs that warn visitors not to disturb the patients are usually blue. According to research, it is the most popular colour so people accept the warnings more easily. Another rather obscure example is that children’s wards are brightly-coloured in order to cheer them up and make them feel energized while the patients who are going to have an operation are most likely to be placed in a monotonously-coloured room so they will not get over-excited or extremely nervous about the surgery. Overall, colours play a crucial role in daily life even though we might have not noticed before. They secretly change our emotions or even attitudes especially in the case of building decorations like offices and hospitals. With an appropriate application, they could improve efficiency, inspire and delight people.
