Colors and feelings
Colors can affect our feelings. Generally, they can be divided into four kinds. They are calm colors, warm colors, energetic colors and strong colors.
Calm colors  Some colors make us feel calm and peaceful. Blue is one of those colors. Blue can also represent sadness, so you may say “ I’m feeling blue” when you are feeling sad. White is another calm color. It makes you feel calm and peaceful.
Warm colors  Some colors can give you a happy and satisfied feeling. Colors like orange or yellow belong to these. Orange represent joy. It can bring you success and cheer you up when you’re feeling sad. Yellow is the color of the sun and wisdom, too.
Energetic colors  When you feel tired or weak, you should wear energetic colors, such as green. Green can give you energy as it is the color of nature and represent new life and growth.
Strong colors  Anyone who needs physical or mental(精神的) strength should wear red clothes. Red is the color of heat and represent power and strong feelings.
