If you always feel stressed, I advise you to wear blue or white. They will make you feel
relaxed. If you can't sleep well at night, you'd better paint the walls of your bedroom blue, as
sleeping in a blue room will bring peace to both your mind and body. If you can't get good
marks in exams, I think it's good for you to use yellow pens. Yellow is the colour of wisdom.
Some people prefer this colour when they hope for success.
