     Have you ever walked into a room and felt relaxed? It could be because the walls painted blue, a calm

  and peaceful color.

    Sometimes colors can affect (影响) our feelings and moods (情绪). Some colors can make us feel calm

  and peaceful (安静的). Blue is one of these. Wearing blue clothes or sleeping in a blue room is good for

  our mind and body, because this color gives us good feelings. Blue is also the color of sadness, so you

 may say "you're feeling blue" when you're feeling sad. White is another calm color. You should wear white

  clothes if you're feeling nervous. White is also the color of purity (纯洁). Many women like to be in white

  on their wedding (婚礼) day. Green is the color of nature. It can give us more energy (干劲,活力) when

  we are feeling tired.

     Some colors can make you feel warm. These colors can give you a happy feeling. People who live in

  cold weather use warm colors in their homes like orange and yellow instead of (代替) white and blue.

     Orange shows joy (快乐). It can bring you success and cheer you up (使……振奋) when you are

 feeling sad. Yellow is the color of the sun, so it can remind you of a warm, sunny day. Yellow is also the

  color of wisdom (智慧). Some people like this color when they study for exams. For example, they may

  use yellow paper. Red is one of the strong colors. Wearing red often makes us active.

     In short, we can try out different colors if we aren't feeling our best.
