Determine what the main use of your bedroom is going to be before deciding on a color scheme. Go for cool, calm colors if you are looking for a safe haven where you can relax and have a good night's sleep. Green is reminiscent of nature and is relaxing for the mind. Try to paint one wall in a light green to create an airy, spring-like feeling. Accessorize with bed linens in different tones and bring spider plants into the room. They generate oxygen and improve air quality. If you feel quirky, experiment with artificial lawn to carpet your bedroom.
Choose a blue color scheme if you feel hot easily. Scientist Sarah Ernst proved in a study that blue walls make feel participants noticeably cooler than yellow ones, even though the temperature has not changed.
