Different people like different colours. Wearing different colours of clothes shows different moods (情绪). Colours have great effects on (影响) our moods. If we're sad, we usually choose to wear dark colours. If we're happy, we often wear bright colours. So, how can colours affect our moods? What colour should we wear?
If you are feeling sad, don't wear black. It will make you feel worse, not better. Red can make you feel more excited. Orange can make you happier. Green makes you feel peaceful and energetic.
It can also make you think better and get good ideas. Yellow is good for your study. You can be smarter if you are in yellow. Some students use yellow pens, rubbers and rulers because they hope to do well in exams. White shows purity (纯洁) and peace, so wearing white makes you feel calmer.
Black can make you graceful or mature (成熟的). It seems that introverted (内向的) people like black better because it is a protecting colour. People in black seem to be serious (严肃的).
Try to wear bright colours to make yourself happy.
